Of course when you tap the push it does a small push but the second one is always bigger than the first. I found a weird trick to make that second one a bit smaller. Push forward on the left stick to make ur dude hunch over then hold the dark catch button. Then ur push should be a little smaller. It's good when you're rolling already and want a bit of a push but not a huge one. It also gives a nice visual variety with the pushing animation.

Got any more tips for a small push, I'd love to hear them.
