Trackpad Sensitivity

All I want to do is change the sensitivity of 1-finger tap-to-click. The default Apple System Preferences setting does not work for me at all, and the trackpad remains extremely over-sensitive even on the Firm setting.

Settings in BTT's FORCE Touchpad don't seem to be changing anything, and neither does anything in TipTaps. But perhaps these settings are for something else. Taps doesn't seem to have a 1-finger setting at all.

Advice?
