We publish our discrepancy log. Monthly.
FlyIQ commits to publishing its full discrepancy log every month — every case where sources disagreed, every quarantined play, every recalibration event. Other sports analytics products do not. If our data is good enough to coach with, it is good enough to audit in public.
