Coming with a new amateur question:

Does it make any sense to change bet spread or amount of spots in the middle of a session? For example:
I Play a 1-12 bet spread, 1 spot with other players at the table and I bring at least 10 max bets as my bankroll for a 4 hour session (almost zero heat, but I don't behave cynical). If, by having good variance, I get to be ahead by 100 units approx, and I get to play alone or with little company after an hour or two since I started, does it make sense to take the same spread but for 2 spots? Or should I just keep it disciplined and play the same amount for the full session and resize later? What do you all do in this case?

Thanks in advance.
