MGM rewards points wrong?

So I noticed my reward points on MGM totally don't line up with what I've actually wagered the last couple weeks. Like, I'm betting roughly the same as last month but my points are off by a couple hundred. I'm mainly doing live dealer roulette and then some multis on NHL, so I double-checked my play logs and it just doesn't make sense. I heard they "adjust" the points rate on certain games, but they don't exactly make that clear anywhere. Is that happening now or am I just missing something? Anyone else see this kind of shift?

Honestly, it's kind of annoying since I mostly stick to the same routines for the comps and perks, not just for the wins. Switching up my games to maximize the points used to pay off but now I'm second-guessing if it's even worth the headache. If they're changing the points rates, it should at least be clear so we don't keep chasing a moving target. Curious if others are dealing with this or if my account's just glitched.
