Yes, I saw the data once I do not remeber the exact numbers but Tiger aims right of his intended line, and release's the club face to compensate this. Tiger Woods is the best green reader on the planet, and can will the ball in the hole when needed "Clutch Putter".. His stroke is not the best out there, but it is the best for him. That is proof that you don't have to do it perfect to get the job done. David Orr who is a TGM guy had told me about why Tiger released the putte (Toe Closes after impact).. Every one is not going to putt the same way and they are not going to release the club the same way, but all the greats have a connected right elbow. Jackie Burke told me along time ago when I was a Jr. Golfer the right hand is the piston and the right elbow connected is the stabilizer for the piston, if that stabilzer is not connect that piston can push where ever it wants to go out of your control.

So should we strive to keep our elbow against our side? How does it move as the shoulders rock, or in the case of the push basic or piston stroke how does it stay there as the elbow folds?

I might have been mis-leading or not as clear as I should have been!!! You are not going to keep the elbow drove to the body or cemmented, unless you are practicing with one arm. The elbow is going to stay close but have room to move against the body with out uncomfortable pressure of having it glued to your side. The visual I give is you should let it follow the curve of the stomach/side, kind of like the stories of Hogan wearing a hole out in his sweater fromt the right elbow in his full swing. You are doing the same in your putting stroke from the arm rubbing your side.

piston stroke
 

A couple of keys to a piston-style, or push basic stroke is to pre-set the right shoulder down plane for a precision follow through and keep said shoulder motionless. It is a hitting stroke so the right shoulder serves as a backstop for the straightening right elbow. I had very little success with the push basic stroke because I could not control the pace of my putts very well...until Yoda taught me (Alignment Golf) to pre-set the right shoulder further down plane in order to achieve a "deeper" follow through and visa versa on shorter putts etc.

Face Balance vs. Impact Balance
 

Correct me if I'm wrong. I thought that there were two kinds of "balanced putters".

1. Face Balanced (Heel-Toe) "Anser"
2. Impact Balanced (Perimeter weighted). "the Odyssey-white hot,two ball"

There probably exists every kind in between too.
I like putting with my right elbow glued to my side and I like the “Push Basic” stroke. I’ve had days when I couldn’t miss a putt with either one and days when I could make a putt with either one.

Yes face balanced is a twoball type, and heel toe is like an answer. The easiest way to see this is to balance the shaft on your finger, and see if the toe hangs down towards the ground, then it is heel toe. If the clubface is looking at the sky, then you have a face balanced putter
