I would do all that you can to not split your numbers, but if there's no other option, I would split per the xx- -yy option. I think it would be legal (this year) either way. However, all the other pragmatic reasons still stand. It'll be easier for spectators and judges (or refs or whomever) to see, and at the end of the day, that's what matters most. It's the objective of the rules, and if it's achieved, I think the inspectors will let it pass.

That being said, my ruling isn't law. I'll send you a grain of salt later.
