Resolution rules
Rules as stated by Polymarket, reproduced verbatim. Convexly has not independently reviewed them and does not endorse them; the rating's resolution-reliability pillar treats rule text as present but not independently reviewed.
This market refers to the tennis match between Alejandro Garcia Carbajal and Javier Barranco Cosano in the ITF M25 Oviedo Men, originally scheduled for August 25, 2026 at 7:00AM ET. This market will resolve to "Over" if the total number of games completed equals or exceeds 22. Otherwise, it will resolve to "Under." All tiebreaks, including any Champions/Super tiebreak, count as one (1) game. If the match is postponed or suspended, this market will remain open until the match has been completed. A postponement alone will not trigger a 50-50 resolution. If the match is permanently abandoned before completion, or if the match has not been completed by September 8, 2026, 11:59 PM ET, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. The primary resolution source for this market will be official ITF statistics; however, a consensus of credible reporting may also be used.Show the full rules textHide the full rules text

How it adds up: composite = Σ(score × weight) / Σ(weight) across measured + heuristic pillars only. Pending and data-rights-blocked pillars are excluded from both numerator and denominator. Total contributing weight = 70.0.
Caveat: 2 pillars not assessed yet; the score will recompute as the substrate fills in.
