Okay today as I was coasting down to a toll booth I tested cutting the ignition and putting my foot all the way down (I have cable throttle) to reduce pumping. Braking effect was not noticably decreased at 3000rpm (but hard to tell from seat of pants dyno). So I think the charts I've seen on the internet are probably about right, friction is on the order of 100-150 kPa mean effective pressure, pumping is at most maybe 70.
