the defintion of center of pressure is the location of the average of all pressure on the airfoil. which suggests that it's near the bottom of the airfoil, since pressure is lower at the top when lift is produced. I can't find any mention of the vertical location of cp nor any use for knowing if it's on top or bottom...
as for the G in the turn, the whole idea is useless since we don't have a G meter. I'm sure they meant constant G turn, and we agree it's more than 1 G in a level turn.
in both cases the QRC is simply using too many words. that's what you get for reading it. when you're done you know less than before you started!
