Dealer rotation rigged?

Noticed the same dealer kept showing up every few shoes during my last couple of blackjack sessions. Maybe it’s just me being paranoid, but it started after a big run of player wins at the table. Felt like the shuffle and dealer rotation were meant to cool things off quick. I'm usually pretty reliable with my tracking - got a spreadsheet and even snap pics for my records. Saw some weird timing on when the pit bosses would step in too, right after streaks.

Is this just random or are others seeing a pattern with the rotations when big swings happen? Wondering if it's more common at certain times or just my risk management side overthinking things. Trying to keep discipline but feels weird when the routine gets thrown off like that.
