The default animation, when navigating between routes in a cupertino app doesn't look right.

1. it is way too slow
2. it seems as if it's completely linear without any acceleration curves

This results in a very bland and boring transition that doesn't feel native to iOS apps.

I know that I can define my own animations if I define the CupertinoRoute myself, but if I want to use the default router I didn't find a way to do that. I also think that out of the box, the animation should be as close to the native behaviour as possible.
