trackpad, 3 finger click intermittently triggered

This has been driving me nuts for years, and I am not sure what causes it, as its fairly intermittent.

I have a 3 finger click cmd+w for chrome ( to close tab ) Now and then when I am holding 2 fingers and scrolling the tab will just close.

How can I debug or log what is happening, even if my pinky is touching, a click should not be registering, I try to reproduce and I cannot, which makes me think its something else.

where do I start to debug this, increase click debounce or timing, or sensitivity and see if it stops etc..

try increasing the required force a bit:
