I shot 641, tonight, and needed to shoot a 270 to do so.
215, 156, 270.
Had to shoot a 4 pin in the 1st and a 5 pin in the 3rd frames to get that last score.
Wish I knew what adjustment to make in the 2nd game...4 opnes (2 of them splits) and only 4 strikes killed me in that one.
Average is up to an even 199, now.
