There's something here I don't understand. This profile says that
follow-calc-win-end calls posn-point via two 'apply' calls, a
byte-compiled function, and a lambda-function. But there's nothing
like that in follow.el that I could see. Did you advise some
functions in follow.el? If not, what are those intermediate calls?

How much is "A LOT more"? How many physical lines do you have in
typical single window in that Org buffer?
