I played them side by side a while back and went through about 1/2 but came to the same conclusion as Andre; your movement was actually better in the first fight. I didn't want to say that because that can be hard to hear but it happens to most fighters. Rarely does improvement occur in a straight, steady manner.

I am sure you are a student of the game. Try watching Jerry Quarry, Frazier too but not as much, Tyson would be third (you can only fight that style if you are incredibly fit). Quarry-Patterson is a good fight to see.
