I was wondering if anyone used different splits on any% rather than (1-1, 1-2, 4-1, 4-2, 8-1, 8-2, 8-3, 8,4). In case I can't perform this perfectly for the moment.

If you're looking for split location suggestions we'll need to know where you are unable to split. I don't necessarily understand what would be keeping you from splitting after every level.
