See here, Martin makes nice well behaved circuits but you can tune the capacitor values to give a big peak.

Think I only noticed it on smooth asphalt over a small speed range.
Oh, another one I made would vibrate… turned out my rectifier was only catching half the waves.
Ok, so essentially you designed it for Martin's "nice" curve, where the power curve has the same shape as a so-called "critically-damped" pulse response?
