I'll have to check that out...if that's that case, Palmer hasn't updated HTB, which he usually revises frequently enough to keep pace. He still uses Tinseth's utilization formula, which takes gravity into account:

I'd like to see those other threads too...

Here's a real, empirically derived utilization curve:

Utilization is a continuing source of confusion. There is the utilization in the boil, which depends strongly (and asymptotically) on time and moderately on inverse gravity. (There is a temperature component as well, but unless you are using a pressure cooker or live way up in the mountains, it can be ignored.) And then there is the maximum bittering achievable, which depends weakly on specific gravity. Higher gravity means a higher maximum bittering, but it takes much longer. Lower gravity means a lower max., but you get there sooner.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
