How the numbers work.
The short version: preserve what the source actually reported, convert units deterministically, compare only compatible observations, and keep every result traceable.
01
Only reviewed, eligible data gets published.
Before a report appears, we check the source, date, units, classes, and quoted values. Corrections are recorded as a new version instead of silently rewriting history.
02
Reported values stay reported values.
A source range, reported average, weighted average, top quote, selected sale, and individual lot are different statistics. We store and label them separately. Missing is not zero, and an unknown head count is not zero head.
- Reported range
- The low and high values printed by the source for a defined row.
- Weighted average
- An average explicitly reported with its source weighting—not a midpoint we inferred.
- Top quote
- A high-end or top-of-market statistic that stays out of ordinary range aggregation.
03
Units are explicit.
A hundredweight, written cwt, is 100 pounds. For U.S. dollar liveweight quotations, the per-pound value is the per-cwt value divided by 100. Per-head prices remain per head unless a corresponding weight supports a clearly labeled derived conversion.
$355.00 per cwt ÷ 100 = $3.55 per lb04
Regional references need enough compatible markets.
Our beta rule requires at least three independent markets with compatible species, class, weight coverage, quote basis, and freshness. One eligible contribution per independent market and sale window prevents mirrored reports from receiving extra weight.
market midpoint = (reported low + reported high) ÷ 2regional reference = median of eligible market midpointsThis would be labeled an unweighted median of eligible market range midpoints—not an appraisal or a volume-weighted average sale price. No regional reference is currently published because the beta has only one eligible benchmark market.
05
The calculator models gross proceeds.
For a compatible per-pound source range, gross low or high equals head count multiplied by weight per head and the corresponding price per pound. Fees, commission, hauling, and shrink are separate deductions and never silently assumed to be zero.
gross = head count × weight in lb × source price per lb
