I have a quest 1 and often have to recalibrate my trackers, but from what I'm seeing it's mostly happening when the quest offsets its tracking for some reason. It seems that it's tracking is shakey depending on where I am in my room, probably due to the lack of markers, puting some brown duct tape with different patterns in the room kinda helps.

Regarding 3.0 vs tundra : stay with 3.0. Tundras are not as high quality, I suspect that they tend to overheat if you dance with them for more than an hour, so some just stop being tracked at some point.
