(20 + 14.7) x 74/69 - 14.7 = 22.5
(20 + 14.7) x 74/70 -14.7 = 22

Looks like my math was off, but I don't mind. As long as I don't see any codes I'm happy. I can deal with track IAT's when I cross that bridge. I've already added a larger H/E as well as the stocker, so I've got a head-start on getting the temps under control.
