The rule is that a number on this site has a document behind it, and the document is the primary one: the regulator, the company, the court, the paper. Not a summary of it, and not somebody’s account of it.
Three things can be true of a figure here. Most have a document we have read, and it is named below. Some are claims made by a named party where we could reach the claim but not the data underneath it, and those are marked not verified. A few move over time, a citation count for instance, in which case we name the live source and treat the number on the page as a snapshot. Not verified means we could not reach the underlying document. It does not mean we doubt the claim.
Where we do doubt something, we say that separately, and we correct it here rather than quietly on the page it came from. There is one correction below.
Supports the left-hand column of the sampling-gap figure on the home page.
Do not apply chlorine ahead of filtration, because any dose of chlorine is expected to lyse cyanobacteria cells.Also the dose ranges: 3 to 10 mg/L of PAC in normal operation, 10 to 40 mg/L during an event, and feeder capacity of 40 to 50 mg/L strongly recommended.
A minimum of two weeks of PAC storage dosed at 40 mg/L or greater should be kept on site or be readily available from the manufacturer/supplier to meet demand.Note the wording is should. This is guidance, not a mandate, and the site says “recommends”.
For Domestic orders, we aim to be able to facilitate delivery within 2 weeks from date of Order, and
In the case of Algal taste and odour events, we can often have a truck dispatched within two days.
No New Zealand supplier, utility or regulator publishes a PAC lead time, a stock tonnage or a delivery term. We searched supplier sites, council asset management plans, drinking water safety plans, long-term plans, Taumata Arowai’s rules and the Hinekōrako public register. The statement that one permanent municipal PAC dosing plant exists in New Zealand is therefore a statement about the published record, not a survey of the country. No public dataset lists which plants have PAC feeders, and the Hinekōrako register cannot be filtered by treatment process.
Acticarb states it holds stock in Auckland and Tauranga but publishes no quantity. Ixom lists PAC for New Zealand in 20 kg bags with the origin given as Australia, China or Sri Lanka, and does not state whether bulk quantities are held locally. Activated Carbon NZ in Taupō describes itself as the only New Zealand producer; its annual tonnage is not published.
The reading of Ardmore’s silos as about a day at full rate assumes a PAC bulk density of 0.25 to 0.5 tonnes per cubic metre. The grade used at Ardmore is not published.
We could not obtain the measured toxin concentrations in Salem’s treated water in 2018, or the concentrations and population for the Carroll Township, Ohio advisory in 2013.
Two things a technical reader should know. NOAA already operates a five-day toxin forecast for western Lake Erie, and Toledo has run phycocyanin sensors at fifteen-minute intervals at its intake. The gap described here is real; being first to close it is not a claim that survives in that geography. And we found no New Zealand drinking-water cyanotoxin advisory in the public record. New Zealand exposure here is prospective, not historical.

agrees to monitor the ethylene levels of the Kiwifruit throughout the storage periodand must notify Zespri of readings above acceptable levels. This obligation has no counterpart once the fruit is in a container.
In 2025, claims on fruit sold from November reached as high as 22% - more than one in five pieces of fruit failed to meet our standards.This is a late-season figure in a discussion of the China market, not a season-wide rate. The season-wide claims rates are the NZKGI figures above.
The recording interval of the TempTale and wireless loggers as configured by Zespri is not published, and the manufacturers do not publish sampling intervals on public product pages.
We have no sourced figure for the value of a single rejected container, and none is used. A per-container value can be derived from export value and tonnage but the trays and tonnes per container are assumptions, so we do not state one.
We could not establish whether reefer setpoints can be changed remotely mid-ocean on any carrier’s public documentation, and we found no kiwifruit-specific marine cargo insurance claim data.
An earlier version of this argument said the damage passes between two logger reads. That was wrong and has been removed. Reefer controllers log continuously at 15 to 120 minute intervals and there is no temporal gap for a thermal excursion to hide in. The gap is the variable, not the cadence.

Only variety in R’s moves can force down the variety in the outcomes.Pinpoints are read directly off the printed page.
The page number for the formal theorem in Conant and Ashby is unconfirmed. The copy read is a re-typeset edition whose pagination does not correspond to the 1970 journal. The quotations themselves are verbatim.
Whether the proof has been criticised or qualified in the citing literature has not been checked. A fifty-six-year-old theorem in a small field has very likely been examined, and if it has been qualified we would rather cite the qualification than be shown it.
Requisite variety is used here as a frame, not as authority. Whether any particular system possesses variety adequate to the living system it manages is an empirical claim about that system, and nothing on this site asserts it.
Six shapes of the same problem. Five of the six carry a qualitative statement of cost rather than a figure, because we do not have a figure we can source for them. The sixth carried a number, and it was wrong.
That card previously read ~30% daily milk lost, summer versus winter
. We traced the figure, and it does not support the claim. It has been replaced.
Where it came from. Altyeb, Absy, Ghanem, Sharawy & Hassan (2025), BMC Veterinary Research, DOI 10.1186/s12917-025-05039-6. One commercial Holstein farm in Ismailia Governorate, Egypt, over 2023 and 2024. Summer THI 79.0, winter THI 59.1. Daily milk yield 31.2 kg in summer against 40.9 kg in winter.
The arithmetic was wrong. The gap is 9.7 kg. Against the winter figure, which is the right denominator for milk lost, that is 23.7 percent. Against the summer figure it is 31.1 percent, which is winter expressed as a premium over summer, a different statement. The 30 percent was the second number used as though it were the first.
The population was wrong. The paper describes the cows as housed in traditional farms with free, semi-shaded yards equipped with electric fans
. That is not cooled confinement. The card describes housed Gulf and desert dairy, which is the opposite kind of system. The study also had 25 cows in the summer group against 93 in winter, and does not report days in milk, so the gap is not attributable to season alone.
The magnitude is wrong for cooled barns. Published temperature-humidity slopes for hot climates run about 0.25 to 0.47 kg per THI unit above a threshold near 72, which puts a rise from THI 60 to 79 at roughly 3 to 9 percent, not 30. And Baladna, the Qatari dairy usually cited in this context, reports the opposite: 36.6 litres per cow per day in 2021 against 36.7 in 2020, a fall of 0.3 percent, through what its annual report calls the hottest summer in four years
, with our essential cooling systems… functioned perfectly
.
Which is a better argument anyway. A well-run desert herd is not losing thirty percent of its milk, and the people running one know it. What Honig and others measured is the gap between adequate cooling and intensive cooling in the same barn, and that gap is about a tenth of the milk. The question is not whether the cooling exists. It is where the finite water, power and labour behind it should go on any given day.
These lists also appear at the foot of each deep-dive page, where they belong with the argument. They are repeated here so that everything the site asserts sits in one place.

Deliberately absent from the water page because we could not source them: the measured concentrations, population served and advisory duration for Carroll Township in 2013, which official presentations reference without stating; the measured raw and treated concentrations at Salem in 2018; a citable colony flotation velocity; the total elapsed time for an ELISA plate run; and a New Zealand powdered-activated-carbon procurement lead time in days, for which no supplier, utility or regulator publishes a figure.
One further absence is itself a finding. Extensive searching found no New Zealand drinking-water cyanotoxin advisory or maximum-acceptable-value exceedance in the public record. New Zealand’s exposure here is prospective rather than historical, and the water page says so rather than implying a local precedent that does not exist.
Two official Toledo figures are not reconcilable and both are given where used: the MMWR reports 3.19 µg/L in drinking water while an Ohio EPA chart peaks at 2.50 µg/L. They are likely different sampling points or laboratories. We do not average them.

Milk yield of lactating dairy cows is negatively affected by heat stress when average THI exceeds 68; the four to five kilograms a day carry-over into the following lactation; the effects on the calf. doi.org
Currently, an acceptable THI limit for high-producing dairy cows (above 35 kg·day−1) is up to 68.This is the peer-reviewed restatement of the threshold. The original re-evaluation, Zimbelman and others (2009), is conference proceedings rather than a journal paper, so it is cited through this review. doi.org/10.3390/ani15020249
We milk our cows three times a day. So, we keep our cows cool by doing these three cooling cycles every day.A teaching page rather than a study; it reports no production or fertility figures, and none are used here. dairyschool.co.il
Deliberately absent from that page because we could not verify them: a temperature-humidity index day-count for Doha or Qatar; the corporate or confinement share of Egypt’s dairy herd; herd sizes for NADEC and Al Safi in Saudi Arabia; a Baladna milking-cow split, a 2023 comparator for its 2024 yield, or any 2025 herd figure, none of which the company publishes; a committed Baladna project in Egypt or Nigeria, both of which exist only as trade-press reports; and the housing-type breakdown for US Southwest herds.
The St-Pierre and others (2003) heat-stress cost figures are widely quoted and are not used on that page, because every route to the primary text was paywalled and we would only have them at second hand.
Three findings are reported on that page specifically because they cut against the argument: Baladna’s own published yield shows no hot-climate penalty; the closest published trial to what we do found no gain in raw litres; and the one randomised trial that follows a cooling allocation decision through to fertility found the allocation made things worse.
The largest gap is an absence, and we characterised it rather than assumed it. We searched for a controlled study that varies a cooling policy on unchanged equipment and measures conception rate or next-lactation yield. There is not one. Roughly forty searches and forty-five documents, including the full citing list of Levit and others (2021), four recent reviews, two doctoral theses, and the conference and extension literature. Elsevier, Wiley, PubMed Central and the ADSA abstract archive all blocked automated access at some point, and the abstract archive is the one place a poster could still be hiding. Separately, we found no study at all in which a forecast, rather than a current reading, drove a cooling decision with a measured animal outcome.

Every claim about a scientist on this site is a claim about a public record. Each name links to that person’s Google Scholar profile from the team section on the home page, which is where citation counts, h-indices and publication lists can be checked directly and where they will be current rather than frozen at the date we wrote them.
The individual credentials on the team cards are stated on the strength of the public record rather than a document we hold. That covers: 13,200+ citations, Clarivate top 1 percent and ARC DECRA (Bergmeir); AAAI Fellow, ACM Distinguished Scientist, Google Eureka Prize and h-index 71 (Stuckey); top 0.75 percent most-cited AI researchers and the ACM Transactions on Probabilistic Machine Learning co-editorship (Buntine); ARC DECRA, third globally at the NeurIPS 2021 ML4CO competition and PhD TU Delft (de Nijs).
The same applies to the three aggregate figures: 50,000+ citations across the team’s work, 1,000+ combined peer-reviewed publications, and top 1 percent Clarivate highly-cited in forecasting. Citation counts move, so any figure of that kind is a snapshot. Treat the Google Scholar links as the live source and these as approximations at the time of writing.
