Actually, Pluto, that' s where YOU' RE wrong. Untill 1988 there was NO restriction on letoff because it wasn' t needed.
I was wrong about the 50% just as you were wrong in your statement that the 65% rule was " P&Y rule all along" . That is just flat wrong. It has only ben a rule for 15 years. It will soon die the death it deserves. RIP
Face it, those of you that don' t want this change are in the minority. You rule will end.
