I also push quite hard when I do DNF,because as far as I know hands consume more air that legs,so it's better to push off hard once that to do one or two strokes with your hands.In DYN i push gently.THere's also one thing that I noticed.
I's far more "dangerous" to "speed up" during DNF than in DYN.It's more likely that you'll experience a samba or a blackout if you accelerate quickly(at the end of your dive) in DNF than in DYN.
