Illustrative sequence. An earlier quote does not stay current while a market is unavailable.
What changed
The retained SharpFish coverage for this selection expanded across observation times. That is an availability timeline, not a claim that each sportsbook first opened the market at those moments.
Why the observation matters
Cross-book comparisons depend on which books have valid quotes at the chosen time. Treating a missing book as if it shared another sportsbook’s number would invent a quote.
What it does not prove
First observed by SharpFish is not the same as market opener. The sequence does not prove when a sportsbook originally posted, why a quote was absent earlier, or whether a technical or provider condition caused the gap.
