you should always do your adjustments to the joystick settings while in the aircraft. When not in DCS, the settings in configurator directly affect the feeling of the axis. I.e., %100 spring force will be the max the rhino can give you. But what it is really doing is setting the upper boundary for a parameter.
As a highly generic example, a sim like DCS will say "give me %50 spring force". That's not necessarily the same as what you would feel with the configurator slider set at %50. What it will result in is %50 of whatever the current slider value is at. So if DCS said %50, and your slider was at %80, the feeling would equate to your slider being at %40 when not in a sim that is commanding the joystick via FFB.
Hope that made sense
