The table is also printed on the boxes that most Michelin tires come in.
Looks like a roughly linear relationship (NB, I am not a mathematician).

If correcting PSI for body weight per the above graph, what are the different riding characteristics (harshness, stickiness, rolling resistance) of a heavier vs a lighter cyclist??

Perhaps a lighterweight person can safely use less PSI, and have a less harsh ride? Or does lees PSI translate into the same ride as more PSI for a heavier cyclist?

Any physicists out there?
