1 · Open-market count over time
Live selection count over the match. koth-prod at each 2s poll;
OO AI at the comparison cadence (~30s). Dips = markets vanishing in bulk. Red dashed = wickets.
The solid black line marks match start — pre-match time (if captured) is compressed into the left
12% so the in-play action gets the room; axis ticks read −Xh pre-match then +Nm from first ball.

5 · Cricinfo vs OO event-detection lag No matched Cricinfo↔OO events in this log (need match_event records from a live match).
3 · Markets missing in OO AI
Specific markets the other side priced (at any point in the match) that OO AI never offered once —
genuine coverage gaps, not flapping. Grouped by market type; expand a row to see exactly which selections /
lines are absent. (Markets OO AI does offer but that blink out are flapping — see §2, not counted here.)

4 · Median price level — koth-prod vs OO AI vs books
Median decimal odds on the common basket (markets all three price, mainline). The gap
between lines is the pricing divergence; OO AI is dashed so it stays visible where it
overlaps the books line.
