Obviously correct, but you're not talking about total stress on the gym floor - you're talking about the stress on that poor bottom fella's feet. I'll definitely concede that resting in a shotgun shell, the top pellets experience less stress than the bottom ones. That hasn't been what we were talking about.
Again, back to shot columns, I think we're actually talking about force per square inch, which would be greater the smaller the cross section of the column assuming total force is the same. That is different than the statement that total force is greater for a longer column.
