played voisins and tiers for 50 spins and somehow missed every section i covered

Played neighbors and thirds for 50 spins last night - put equal units on voisins and tiers and somehow managed to blank both for the whole session. Kept looking for some sort of tilt in the wheel or maybe a dealer signature, but nope, just pure variance eating my stack. Even doubled a few times thinking surely the drought would break, but it just ate more. I’m honestly wondering how common this is, or if I just ran into the world’s coldest shoe.

Usually I try to keep a calm system in place, steady bets, don’t chase, but that was probably the most frustrating stretch in ages. Anyone else get these cold streaks where nothing covered seems to hit?
