That's a good question that a lot of people don't have an answer to, and I don't know if I do either.
It is cool though....if you do some SAE research, you'll find that they can rotate up to around 10 rpms depending on several variables. Sometimes they can rotate at 1 rpm or slower.
The ring manufacturers always give their recommendations as to where to put the rings....so I do as I'm told and go with it.
When you jerk an engine apart though, the gaps can be all over the place.
