Evolution table limit?

so i've noticed lately the live blackjack tables keep shifting their minimums and maxes way more often than before. like, i used to see steady $5/$1000 or $10/$2000 for weeks at a time, now i log in and sometimes tables are up at $50 min or the max drops out of nowhere. saw a high roller table cut their max in half right in the middle of the night last week, which really threw me off mid-session. doesn't help when you're planning on doubling down with a bit of a martingale backup.

has anyone figured out a pattern to how these limits change? i started tracking time of day and weekday but can't see much consistency. thinking about switching to something more stable since i hate adjusting strategy every time they move the goalposts. does anyone else keep data or have a tip on which live dealer tables stick to their limits longer?
