Across the ten bouts that produced a result, five ended by knockout, three by submission and two on the judges' scorecards — eight stoppages in ten fights. Every decision was unanimous: not one result divided the judges.
The quickest finish belonged to Laïd Zerhouni, who stopped Bartosz Fabinski after 13 seconds, and three of the eight finishes came inside the opening round. The longest was Szymon Karolczyk's submission of Artur Krawczyk, 9 minutes and 54 seconds in. End to end, the ten fights filled one hour and 9 minutes of cage time.
The main card finished at the higher rate: five of five, against three of the five below it. Ewelina Woźniak (submission, round two), Marek Samociuk (knockout, round two) and Szymon Karolczyk (submission, round two) all closed before the judges were needed.
Seven weight classes were used, heavyweight most often with two bouts. KSWTV carried all ten bouts, split across a main card and one preliminary block.
