Saved decimal win-price comparison across identical complete fields. Best-price frequency includes ties; price gap is 100 * (maximum / minimum - 1); overround is 100 * (sum(1 / price) - 1).

First ten races by complete-field bookmaker coverage, then bookmaker count and scheduled start. Selection did not use price gaps, leaders or results. The same five sources priced all 71 matched runners. Verified Mount Isa/Mt Isa aliases were counted once.

One saved-feed observation across two meetings. Source metadata was 10.7–24.3 minutes older than capture; those timestamps do not prove when each bookmaker last changed its price. No closing-price, movement, outcome, executable-price or profit claim is made.
