I have not heard of the 10% rule, but I do know that the factory recommendation of 42psi is for cold tires (and typical load). So filling less than 42 cold would mean they will be under-inflated (per the recommendation). It is pretty common to under-inflate when trying to increase friction for stickiness... but too far and the handling can suffer greatly as the tire distorts under side load (and the friction in the sidewall can wipe out the tire life pretty quickly; of course that is expected on the track).
I expect the pressure to go up a couple of psi when warm (which it typically does). I can't recall if Kawasaki's system tries to compensate for temperature. I hope it doesn't because that would make no sense to me at all- when I look at a reading, I would want to know what the pressure is, not what it thinks it should display to me so it appears like it is always "correct."
Speaking of tires, I have my appointment tomorrow to mount my new set, finally!
