24.......
Ahhh crap! I went and read a few posts and was ready to quit. Went back to the page and saw the ball laying on the diving board so thought I'd give it a whirl. Made it. You just need to go over the edge with some momentum so the ball doesn't fly off the board; after that its easy.
I guess I'll try a few cracks at 24......

Only problem is that the ball was sitting there for about 10 minutes and so my time is all screwed up now? oh well, glad to be onto the next level.
