well, to add on to DGman's view, one is "Objective" and the other is "Subjective"
Conforming to Groove is "Objective"...as long as the groove design meet the requirement, there are barely any argument about it.
However, my thinking is, if the groove rule can be more stringent, Ping Eye2 wedge could be "non-conforming" also
Conforming to the spirit of goove change is pretty "Subjective"....and somehow, each say their own story...and i guess this argument will never end...keke
just my view...
