Please stop pushing this nonsense about playing only good cards in zoom. If you mean full ring, then obviously they are tight, because the whole idea is to be tight on early position. Good players have as wide ranges as 6max on later positions. Tight is right, but that translates for reasonable tags on 6max zoom playing around 18% - 24% of
hands, on average, that means his blind ranges are again tight, but still around 35% - 42%
Just repeating shit over and over again does not make it correct
Let say you play only QQ+ that would translate 1.36 hands played per 100. During that time you would lose 25bb solely as a blind cost in 6max. And no way have you will win it back during those 1.36 hands.
So interestingly enough, the minimum % hands we need to play if we assume we win the blinds 6max every time we open is once per orbit, giving us minimum range of 16.67%
