Have you ever tried reducing the expander ball slightly by polishing with a very fine abrasive?
It increases neck tension which might help with your variations?
You don't intentionally remove anything just buff it to a mirror shine. The removal of high spots from the machining does shrink it a G.B.H. though. I chuck it in a power drill & use Green ScotchBrite.
Its one of my little accuracy tricks.
