Good catch! Will correct!

Milos video is coming up Pete Sampras.

A little tedious for regular on court work, but accurate. Eventually there may be more accurate systems.

Thanks

You can do it with a casio or other high speed camera that records at 240 frames and has a shutter. But you have to manually count the rotations and do a little algebra. I do it all the time. Although Play Sight comes up with rotation output when Brian and I tested it against the camera it was correct or close on maybe 50-60% of shots only

John -

Is there an affordable device that measures rpm (spin rates) on shots like the pocket radar does for mph?

[johnyandell]

I would agree with you. Too far.

Stotty,
Great question... I think that as long as we use terms like "Continental" there will always be slight differences in definition. Kerry's view to me is slightly stronger as you say than Scott's. You can hit a slice with either but I like the slightly less strong version.

My analysis:

It's a good article, thank you.

I have a girl whose heel pad is edging towards bevel 8. It seems to inhibit a correct, flowing follow-through. Do find this is the case with players you've come across?

[johnyandell]

Apparently yes. You see elite players work hard to create that cross over closed stance and you can actually see more hip and shoulder rotation in the high speed videos. As Kerry has pointed out though lower level players should work on the outside leg set up and coiling-- and then they are in great position to step neutral with great alignment and effect.

If a player closes the stance on a backhand, does it give greater power than one struck off a neutral stance, due to more coiling and rotation? I realise stances are situational but just wondered which gives the greater payload on a backhand.

[ferli001]

Right, hadn't thought about that .

[johnyandell]

Good thought. We are in the middle of a big conversion to a friendlier mobile so not something we can think about now. Why not just copy the url and past it somewhere though?

[ferli001]

Hi John,
I had an idea that it might be very useful to the viewer, like me, who likes to browse through videos and lessons, to be able to add a bookmarks or add the page to a list of "favorites" so that when I want to return to the video I can just look it up at my marked sites -- rather than remembering where I found it -- but I don't know if and how this might be done since I am no techy. Its just a thought

[johnyandell]

Hey they play at high speed!

[stotty]

In 'The Lessons of Pancho Segura' can you slow that clip down at the bottom of the article. It's running like a Charlie Chaplin movie on steroids.

Sorry ignore this message. it seems to running at normal speed now...weird.
