Putting Ball Position/ Where and Why?

[TomDonS]

What have you found to be the best ball position for putting. Blade or Mallet. Any kind of grain or grass. Looking for a happy medium so I can stop over analyzing.

From Dave Pelz Putting Bible:

"Any putting stroke that swings in an arc suspended from somewhere around your
sternum (or some other spot between your shoulders) will have a bottom to its arc,
a low point, a place where the sole of the club is closest to the ground. I have found
that the best place to position the ball in your stance is approximately two inches
ahead of this bottom point. At this spot you have the best chance of striking the ball
on an ever-so-slight upward arc, as your putter comes up from its lowest point
(Figure 4.10.1). Striking the ball slightly on the upswing gets putts rolling on top of
the grass without lofting them too high, which produces bounce, or hitting them
down into the surface of the green so they squirt off to the right or left."
