Fighting styles are needed!
I don't know if you know, but I didn't so I put this here.
You need to have learned all three fighting styles at least once if you want 100.00%. I found this out when I had 99.47%. I didn't know what I needed to do to get 100%, so I was just fooling around.
I was in SF so I went training in the Gym, when I was done I walked up to the trainer, accepted his challenge and beat the crap out of him.
A few minutes later I was shooting at some Aztecas and noticed that I had infinite bullets. Go figure .
