no, rpm doesn't have a direct effect on coolant pressure, but the more heat is generated by the engine the higher the coolant temp is, and with constant volume you get increased pressure.

you shouldn't be filling the coolant that many times. I think you're still leaking. You have any wet spots under the ET?
