There are books written on this ‘Little Critical Stroke’ … 40% to 60% of the score. Here are a couple small details for you. Hope they are useful and helpful?
STANCE … Width is best on the narrow side with feet ‘Under Your Armpits’. Need to tell you, however, that there have been some very efficient and successful ‘Putters’ who employed a very wide stance outside their Shoulder Sockets. Why? Because it somewhat locked up the user’s hip sockets. This stabilized the tendency to ‘Get Lateral – Sway & Slide’. Needless to say, this tends to make your ‘Pivot Axis and Clubhead Control’ a bit of a hazardous crap-shoot.
… Foot Aim is important. With ‘Putting’, because there is ‘No Pivot’ required ‘Square Square’ is suggested.
WEIGHT DISTRIBUTION … The general preference is ‘Even or 50-50 Left To Right’. Your ‘555 Team’ often suggests that one ‘Slightly Pre-Load His or Her Target Foot’. (2% to 5% more on the Target Foot) This lead or Target Side Pre-Loading’ (Impact Fix) tends to stabilize the ‘Pivot Axis’ on its ‘Lateral Post’. There is no ‘Weight Shift’ with a ‘Giant Blue Heron Finish & Hold Catching A Frog’… what lightning speed and leverage!
‘Tinker Time – Time For A Feel’!
‘Consistent Precision’ matters!
