your comments are good, it means you understand some things
but to do better you should dive a bit deeper in it
the main problem you should get too much info at once, it's not easy. I propose you this: run freak clincher type. it allowes you not to think about style and your tactics much, this type does the same thing nearly always.
the build is something like this
Strength 29
Knockout Punch 0
Speed 15
Agility 1
Chin 11
Conditioning 13
Cut Resistance Low
Winning Streak
Rating 0 Status 0
Height 5 feet (152 centimeters)
Build very heavy
Weight 160 pounds (72 kilograms)
Minimum Weight 154 pounds (69 kilograms)
any weight from welter till cruiser
the tactic is to wear your opponent out and finish after. the basic FP for him is
1) 4B/8/8 (clinch);
if round > 3 then 5B/8/7 (clinch);
if round > 6 then 5B/9!/6 (clinch);
if mystuns > hisstuns then 4B/6/10 (clinch);
if score = -4 then 7/6/7 (clinch);
if round > 6 and score < -1 then 7/6/7 (clinch);
if round > 8 and score < 2 then 8/6/6 (clinch);
if opponent = tired and endurance_percent > 67 then 6B/9/5 (clinch);
if (round - 12) > score then 6H/11!/3 (clinch);
create a few similar guys, give them this FP and check how it all works
