I stopped the video and wrote down the "in-fight" time, because I wanted to know, how much time I have in each fight.
Round 1: 25 sec
Round 2: 36 sec
Round 3: 29 sec
Round 4: 98 sec
Round 5: 100 sec
Round 6: 247 sec
Round 7: 209 sec
Round 8: 140 sec
Round 9: 98 sec
Round 10: 303 sec
That comes to a total of 1285 sec, if I didn't make any mistakes (maybe I did).
And that would be over 21 minutes.
