Learn to love firm brakes. Bleed them frequently. There is nothing worse than excessive pedal travel to screw up your driving.
Since I ride rentals these days, I am deeply experienced in crappy brakes. This extra travel associated with un-bled brakes is a killer to speed imho. You really don’t need to be spending the first 5 laps finding how to modulate 1/10th the normal brake pressure.
It’s massively in-exact and totally fixable with 5 mins work. Brakes should be consistent. As an owner-driver, that’s totally in your control.
Also, rotation is important. Braking is often a part of rotation. This is too critical to have to dance around.
One way to think about this is that it takes a tenth of a second for the message to reach your foot from its origin in your brain. Crap brakes make that even longer as your foot has to travel to the end of the throw to initiate bite. That’s another .05-.1. Until you adjust, you will be slightly off every braking zone.
