Is there a spatial map for 2020 MacBook Air track pad's right-click "sweet-spot"?
Solution 1:
The options for right-click are configured in System Preferences > Trackpad. You can either initiate a right-lick with two fingers, or in the bottom right or bottom left corners.
I don't know what the default is, so perhaps it's set to use two fingers, and there is no 'sweet spot'. Personally, I prefer using two fingers, as it prevents accidental right-clicks if you happen to be 'in the zone'.
