Across the nine bouts that produced a result, five ended by knockout, three by submission and one on the judges' scorecards — eight stoppages in nine fights. Every decision was unanimous: not one result divided the judges.
The quickest finish belonged to Adrianna Kreft, who stopped Karolina Owczarz at 1:16 of round one, and three of the eight finishes came inside the opening round. The longest was Werlleson Martins's knockout of Patryk Surdyn, 10 minutes and 30 seconds in. End to end, the nine fights filled one hour and 8 minutes of cage time.
The main card finished at the higher rate: five of five, against three of the four below it. Kamil Gawryjołek (knockout, round one), Maria Silva (submission, round two) and Filip Stawowy (submission, round two) all closed before the judges were needed.
Six weight classes were used, heavyweight most often with three bouts. KSWTV carried all nine bouts, split across a main card and one preliminary block.
