Animation Sequencing 2

This is a slightly improved version, as the animation is now less out of sync.
Unfortunately, the fade in and fadeouts for leaves 1-3 are still screwy, and go in reverse for some reason after the first pass, while still fading in.
Why?

I tried playing around some more with the animation time values, but this did not fix the problem.

 

Puzzling…

WHAT IS GOING ON HERE ?
