#!markdown Good question. I think the way to answer it would bike this: The riders weight was 190lbs. Now, according to the Rockshox sag chart, that would imply a starting weight of approx 80psi. Now in the test, the rider began at 84psi. So, the starting value is already a bit high. Assume 80psi was more accurate with ZERO tokens (which is the default for such a long travel bike). Adding 3 tokens from none, you could approximate 15psi (3x5psi) drop in pressure which takes you to 65psi. I say 'approximate' because each additional token has less effect than the previous, i.e it's non-linear. Which is basically where the rider got to at the penultimate tune. He then dropped another 5%, probably due to the conditions of where he was riding. So the numbers make perfect sense to me. FWIW, I have done a lot of testing with suggested pressures (RS) and lowering significantly as in this above scenario we are reading about. I really feel the fork works better at around 20% sag than 25%. And 30% is crazy. At 20% if you speed up the rebound and add in enough LSC, I find the fork is more supple ironically because it stays higher in the 'nice zone'. Also, faster you ride smoother it becomes. Try to get your tyre pressure as low as you can to eat the small stuff too.
