... it is hard to fathom ... Would not be the first time we get lost in the weeds.
Dude, You're the guy who
asked. No one is lost in the weeds but you. You can't fathom the pucker factor when your foot goes another 3/4" at 100 mph? Really?
Yes, really, I only push hard enough to accomplish the task, and if one is so set in driving our non F1 cars that the idea of pushing 2% more fluid volume is a huge problem, you might want to stay in the weeds (every turn, every second, every time, every wind shift, any fuel consumption, etc requires a new/different braking pressure as conditions vary) (I have no idea where your 3/4" number comes from) (and if you are getting 400F fluid temps, you are on the proverbial edge in more ways then just fluid temps) ( a sudden 400F fluid temp rise would be a rather unusual set of circumstances) Dude.
