What an amazing read! I saw the correlation between actual and perceived ability and thought to myself, yeah, because the further up you go the more you expect the scale to become logarithmically difficult, be it only to imagine (for themselves) that it's even possible they don't get to actually high score (100%). That being said, there might be some statistical magic hidden in the graph, where the group, the further up it goes, does less rely on self-rewarding by guessing a lower score and splitting up into "actual" self-underselling for mimicking, evening out with the ambitious but really good ones.
