I usually put the tip of my thumb and pinky together and then press the palm flesh beneath my thumb first to get a sort of muscle memory as to what I am looking for. Then I press the avocado around the centre and compare. If it is around the same I open and eat. Seems to work most of the time — with the super thick skinned ones I generally press higher up on the avocado (closer to the stem)
