I heard this term or some variation of it in recent PlaneMate talk. There is definitely the word ghost, which is referring to the muscle memory retained after using the PM enough times and then taking it off and relying on the feels to “keep” for the next few swings.
I really haven’t heard that term much before the PM. Instructors have told students to do the pump drill, like 5 times, and then a swing. That is indirectly relying on the ghost effect.
Isn’t mapping relying on the effect as well? And slow practice? It just seems this is something I would have expected more talk of or maybe it just went over my head.
