I checked your fight with one of my dudes. It's not bad. But you someway lost this "H" in the second headhunting attempt in round 6. So your fighter went 5/10/5 instead of 5H/10/5. This headhunting adds 20% to your stun power, not much but still.
Another thing I've already mentioned, the taller your opp is the more aggressive you should be
in short- if your opponent taller or same height with you, you should be more aggressive- start with 9/1/10, 10/1/9
when your opponent is shorter than you, then less aggressive- 7/1/10, 8/1/10
if much shorter then 5/1/14, 6/1/13
So you should write a several variants of the same FP with low, medium and high aggression. And vs tall guys you should use a high aggressive one.
The total number of the points which you spread between aggression- power - defence is always = 20. So 5/6/9, 7/1/12, 10/3/7, 6/7/7, 5/10/5 etc
Check your fights, think them over, try to find a way you could do better.
