The problem that the term " right shldr " created, was the fact that many did NOT use the body-- the term was abandoned by the ISTD and others as an explanation ,and was ammended in the Rev, Techn.to read " side " .
I championed that cause for many yrs .
As to the original Rev. Techn.--- many changes have been made in terminology and techn. ( Alex didnt get it" ALL" , right ! )
Would like to add this to the mix-- the newest theory on rev. turns ( as given by Eggleton )-- a sympathetic or minimised CBM on rev, and the opposite for Nat. turns (closed L.I.L. )
