Knockdowns or “flash knockdowns”, as defined by Power Slap, will not be counted toward the final knockout total. Matches involving a Redemption Round in which a draw is declared will not be counted toward the final knockout count. Only matches that result in a winner by knockout will be counted in the final count. If Power Slap 20 main card concludes early, is shortened, or is truncated for any reason, the outcome shall be determined by the official statistics as recorded by the governing body or event organizers at the time of conclusion.

The primary resolution source for this market will be official information from Power Slap; however, a consensus of credible reporting may also be used.Power Slap 20's main card stacks durable ranked contenders across heavyweight, light heavyweight, and super heavyweight divisions who frequently reach decisions in three-round bouts, muting the recent high-knockout pace seen in events 18 and 19. The five-round lightweight title defense between champion Robert Trujillo and challenger Hayden Johnson adds length without guaranteed early finishes, while coin-toss advantages and cautious veteran approaches in heavyweight matchups like Dorian Perez versus Nate Burnard further tilt toward extended exchanges. Weigh-in stability and limited late scratches reinforce trader consensus that the total will land comfortably below 4.5 knockouts on the main card.
