It’s best to sit down right after the tournament, because you have enough time to sit and wait for the best hand, and you’ll just have time to study your opponents, so my choice is to sit down at the beginning and go for knockouts.
in a bounty tournament you want to be there from the start
late register is ok but you really don't want to miss anything in a bounty game.
other tournaments being late is fine
Always play from the start. If you late reg it most likely the bad players are already out so you don't even have the chance to get their bounty.
Also you won't cover most people which is bad again
