It really depends on the tournament tbh
In hypers i tend to think and act faster, in omaha i think about the hand for a bit if it's getting to a big pot, Also the higher the buy-in the more i want to think about the play im making, If i'm playing 2-7 stud or 2-7 razz,Badugi, i really have to think if i have enough outs left to go for the draw i'm getting,
Sometimes i think to fast and make the wrong call that could save me a few chips
So for everyone it's different some play everything quick some play everything slow some do both, I do both depending on the tournament, if it's hyper i like to play a bit fast, Deepstacks you can play a bit slower imo.
But most mistakes come from a quick decision most of the time.
