So, if I understand you correctly GJS, ensuring hands ahead of the ball at impact has the effect of delofting your putter, yes...???
Or, much the same effect as perhaps having the ball positioned back in your putting stance, as opposed to forward......
As I understand it, all putters come with some marginal (and I do mean "marginal") amount of loft built in.
That said, from a physics point of view, hitting the ball above its equator, notionally on the downstroke, to my mind would squeeze (if only slightly) the ball down into the turf of the putting green, tending I would have thought to decrease the likelihood of getting topspin needed to start the ball rolling nicely along the target line......
Just thinking out loud.....
Cheers
