If your win rate per hand drops, then you need to increase your bankroll requirements inversely.

Not just your win rate is important, but also your variance per hand. If your per hand win rate INCREASES marginally (through tighter preflop play, experience, game selection, etc), but your per hand variance increases substantially (by pushing smaller edges, more aggro games, etc), you will need to increase your bankroll requirements.

I agree mostly with what you say, but win rate is not everything when it comes to bankroll management.
