      Hi John,

      I had a couple questions for you in that thread that just got deleted.

      Specifically, which aspects of MTM technique have you found to be consistent/inconsistent with elite level technique?

      I know that's a big question, I don't expect a fully comprehensive answer, but I'd appreciate it if you could take a crack at it.

      I was wondering if you ever discussed or written about how the front foot often leaves the ground during the forehand stroke of the top pros yet their front foot stays rooted to the ground on their two handed backhands.
      1. Rozroz
        just sayin',
        the front foot in FH CAN be off ground at certain strokes because it's less effective on the axis point of the stroke, and could still be maintained on the back foot if necessary.
        yet in 2HBH, the whole motion is dependent on that front foot, otherwise you'll lose balance (the axis point is more frontal because the 2 hands demand it.

        This is what I'm thinking too but I wanted feedback from a true expert. Thanks though.

      hi John, was trying to contact you through that Facebook page of
      i was wondering whether you still do personal video analyzing for a fee?
      if so, how much? thanks, Roei (Israel)
      1. JohnYandell
        Yes! $250/hour or 10 hours for $1000. If you want more details we can discuss.

      Quick question related to "hitting below center": what's the min/max face angle on a TS-FH you've observed?

      John, to your knowledge, is there any 5000+ fps video of the contact phase for a TS FH?

      Frame-by frame analysis of those 4-5 milliseconds would go a long way in defining the size/shape of the actual contact zone/patch along the cross axis('first contact' through exit) and, by comparing a number of samples with initial ball contact on top-mains 1-5, the zone location tolerance for clean hits vs twisters. Purposely omitting bottom mains, because even first touch on M1 will result in severe twist.

      Would have put this into the thread, but I'd like to avoid getting into yet another pointless discussion with Povl and the other "hitting below center is better" folks;)

      Thx, Andreas
