No idea, but when people say they can visualize an apple and then say it feels like number 1 on that chart, I would say that my experience of whatever I'm doing when I'm 'visualizing' an apple is more like 4 or 5

I can only assume people are trying to accurately describe their own experience so when my experience seems to differ a lot it seems to me that there is more going on than just confusion about wording.
