I found that SBA 30! when it is done correctly that when I look at the ball it seems to generate shiny objects slower, as it is causing the frame rate to drop. If the Skee Ball machine is in view it will generate slower. The lower frame rate can cause the ball to move out of place, ending the 30! generation.
When not having the machine in view. Generates shiny objects faster and has less chance of coming out of place.
I found this out when I was testing the possible bowling speeds for the 30! setup to work.
I hope this helps for other peoples runs!
If you find anything else out let me know!
