Scaling issues...

Human player works the same as last year.

Scaling problems make it harder to make shots.

The goals are only 9" in diameter.

The mobile goal is nearly impossible to get balls to say in -- they hit the bottom and bounce out, even when just dropping the balls over the 6' wall to a goal pushed right up to the wall. The goal is only 18" tall and those hard wiffle balls bounce pretty well on plywood.

The stationary goal is harder too because the goal is only 9" in diameter. Basically, the variation from shooting a wiffle ball 5' toward a goal is not much different than the variation from throwing a playground ball toward a goal farther away. The size of the goal has shrunk but not the variation in hitting the target. Also, shooting playground balls is very much akin to shooting a freethrow, it is a pretty familiar task. It is weird to shoot a 4" diameter wiffle ball, not impossible, but not natural either.

Net result, much lower shooting percentage.

We'll see how this turns out.
