Yeah, we knew it was a problem but didn't have the time to fix it. I believe it might be one of the bigger culprits as well.

There is no exit chute currently. I believe we have far too much compression as well when I saw how little our competitors had. That video was very helpful.

Yes, we played with this extensively. Even with significant back spin we saw no increase in repeatability. When we knuckle-balled the shots intentionally we did see some lateral drift that went away when the ball was spinning.

Thanks much!
