That yellow path is what screws me up. There are two tiles that will randomly send you over the barrier. This path worked every time.

Blue's path is 100% the better implementation of the right side. Nothing more frustrating than getting to the very end and hitting the right side of that last square, launching you up and over the barrier.

Yep, I always run right side and that's basically what I do when I get can over to the left of that tile in time.

I pretty much do this and still face random launches, but mostly, I don't want to move that much distance toward the edge if I can avoid it.

Also, is there any unintended purpose people won't try to use a spreadsheet program for?

I've always run left or middle, so last week was the first time I have done the right side. I was doing the method Dame posted, and I was getting really frustrated. Really good runs were ruined by that last tile. What I posted I learned through trial and error, but I'm glad to see it confirmed. Once I started using that path the only slip up was Kermit and I crashing into each other once. It flipped Kermit to the right and me to the middle for the last set of psions and we got mixed up on who shot which one. We both shot the same psion, and the other one launched both of us.
