How far back?

According to James and Andrej's respective simulations,
------------the lintel shadow puts Frazier front of landing.

If James & Andrej are right (and they seem to be) Billy Lovelady cannot be on the landing in Wiegman or
his face would be half-shaded. Lovelady, at 5'8.5", is NOT a full head smaller than Frazier at ~6'!:
It would be outstanding if someone could produce a scaled Wiegman-to-Darnell gif so that we could make a height comparison of
UPPER LOVELADY (in Wiegman) & PRAYER MAN (in Darnell)! i.e. something a bit more SOPHISTICATED than this crude effort of mine!
