I concede that you two are technically correct. I'm talking about pitch and not incidence, sorry. It's just that I come from the FF world and we think of things a bit differently since the entire stab is in effect also the elevator (no seperate control surfaces). When a plane porpoises or stalls in the glide segment of flight it needs "negative" so we shim up the leading edge of the stab. When a plane dives too steeply in the glide it needs "positive" so we shim the trailing edge of the stab. It's sort of like the way older generations refer to electrical current flow. It's technically backwards from the way electrons really flow but they all know what each other means.
