In general obviously early registration is going to be better for you almost every single time. the more time the more blinds the more chips the more skill will prevail. However, there is something to be said for very late registration, when i play a really low stake tournament its easy to register at the last moment, wait about 3 mins, and ive made the money, which is a nice way to make a dollar or 2, but then you are just playing w luck basically because you are so small stacked compared to the other players. If you want to try a later registration with your
bankroll i believe you should implement a system. If you use 4% of your BR in MTTs, then you should only use at most 3% at mid registration and 1-2% in very late registration, this way you account for the variance and the luck aspect of the game with your Bankroll and it should work out ok that way. Good luck in future event.
