Agreed on the last 2 posts about the inverted track---I know because I have one. Makes drilling a pain in the something or other. As far as this track... I dont know that stuff. I dont know if its necessarily normal. I was trying to think of how you could throw the ball to do this---I drew a blank. Could be a combination of things.
Also...
If you have multiple bowling balls, is this happening with all of them? And if so are they are drilled the same (layout)?
