Marriott would have every right to fix their math and cut the nights count back to what it should be. And while I am happy to make the best use of what is allowed within the rules, I am absolutely not trying to break them. As a LTT member, I am less worried about requalification - and would probably get to 75 nights in the proper way. I had Ambassador level before - nothing I desperately would want again.
I also didn’t mean to suggest the rules have changed - just an observation of what I am seeing this year.
