2. VCOG C.F. = A reduction in MPF points when the iron’s actual vertical centerof gravity exceeds .840".
3. MOI C.F. = Additional MPF points awarded to the actual MOI reading basedon the actual vertical center of gravity.
ABBREVIATION KEY FOR HEADINGS
BASIC VCOG = Basic Vertical Center Of Gravity
MOI = Moment Of Inertia (measured in ounce/inches square)
ACTUAL RCOG = Actual Rearward Center Of Gravity
VCOG = Vertical Center Of Gravity Adjustment
ACTUAL VCOG = Actual Vertical Center Of Gravity
VCOG C.F. = Actual Vertical Center Of Gravity Correction Factor
MOI C.F. = Moment Of Inertia Correction Factor
MPF = Maltby Playability Factor
