If anything, it would be between the two extremes.
Thoughts?
The main thing would be that one part of the ball would be different than the other.
Say you set the ball on the spinner and it spins counterclockwise.
You hold the 500 pad in your left hand and You hold the 1000 pad in your right hand.
You spin the ball, sand and stop.
The side closest to you would be about 500, because it came off the 500 pad last.
The side farther from you would be about a 500/1000 surface, because it came off the 1000 pad last.
