Well you're certainly not alone, I've always wanted sims to include a ''FFB Clipping'' thing, much like a FPS counter, so you could see when the occuring FFB in the sim exceeds the maximum value the game can send to the wheel.. I bet half or more of the simracers run their FF too high.
To have more fidelity you sort of want the maximum actually occuring force feedback (say a hard high speed corner) to correspond with 100% FF being sent to the wheel.
With high FF strength in game, i.e. your 200%, any sort of bump in the road, or even slight wheel turning or slip angle will make the sim send 100% FF to the wheel.. Above that, the force in the sim will change, but it can't send more than 100% to the wheel, so you basically only feel the force until this 100% is reached..
