Shifting Weight during Strokes

In all of your videos, I see that when you do the stroke, you don't explain what should the feet do. I can see Jeff moving his feet. So it comes to mind that he's shifting weight on his legs. Why didn't you explain it? I'm a beginner who followed what pingskills say in the video. I videoed myself and said, Why do I move static? Did I miss something?

 Another follow up question is, why don't you make most out of the 10 mins in Youtube? Or even 5 minutes for each stroke? Remember, you only do videos when your not busy which means that you should make the most out of your videos.

It is iimportant to get the basics right first.  That measn getting the stroke correct.  As ling as you are balanced you can work form there.

We have a limited amount of time unfortunately.  When we shoot the videos we make sure we cover the important points.  Just fillin gup the 10 minutes would be a waste of everyones time.
