What does coverage tell you about a picks record?
Coverage describes how much of a defined record has the evidence needed for a particular check. It is different from the number of successful picks. A record can have many graded results while still lacking the prices needed for a closing-price comparison.
Name the check and the full set
A useful coverage statement names both the check and its denominator: for example, how many published selections have a final result, or how many have a matching closing price. Different checks can have different coverage.
Illustrative example: if eight of ten selections have a matched closing price, two comparisons are unavailable. That tells you nothing by itself about which picks won.
Missing is a state, not a number
A missing observation cannot safely become zero. Zero may be a real recorded result. Missing means the evidence is absent or unusable, and the reason matters.
Pending, void and unavailable are also different. A game still in progress is not a failed selection; a player who did not play is not automatically a loss.
Read coverage beside the result
A summary should reveal what it excludes and why. Tikata’s public copy does not claim complete historical coverage or an independently certified record. Inspect the available receipt and any stated limitation before comparing results.
