The numbers are pretty easy to do. If you multiply the capacitance by the resistance of the TPS across the capacitor terminals you get a time constant. At 1-2k ohm for the TPS (educated guess) and 22uF capacitance, you get a time constant of 20-50 msec. This seems quite short in mechanical terms, so I'd be surprised if the effect is significant.
