    My Journey to 6.0 Has Ended... Can I Still Improve? (TennisProdigy Video Diary)

    You mean in the sense you would have similar shorts and shirt, and you also be holding a tennis racket, right?

    wait, you are computer rated USTA 5.0 right now?

    An 88 mph first serve is more than fast enough to beat you.

    I actually think most TW posters do not play tennis at all........

    Tennis Indoor facility for one month

    Weighting up the Crossguard of my Sword

    please, that is such a misrepresentation. I'm really sorry you keep doing that - you seem a cool guy overall. We have discussed Stoneage's view on this topic in the past: MgR/I was never incorporated into his app. The calculator was for some time provided on his web site in 2010. Even that...

    Weighting up the Crossguard of my Sword

    We have been over this MgR/I thing many, many times. There's an excellent math-backed analysis of this concept. With a _very_ telling title: https://tt.tennis-warehouse.com/index.php?threads/mgr-i-is-useless.352140/ (in case one is wondering the author of that thread, @stoneage, is the very...

    Weighting up the Crossguard of my Sword

    sure, I can do 'the measurements' with proper tools. What would you want me to measure? sure they do not. Is someone claiming they do? Could you please define what is 'pendulum acceleration' in the context being described here?

    sooo, the way I read it the courts at 2021 AO are _not_ per ITF regulations.

    I see what you did here. An epic episode...... :)(y)

    sooo, the way I read it the courts at 2021 AO are _not_ per ITF regulations.

    Here are 2021 ITF regulations: section 1 The Court: " No advertising is allowed on the court, net, strap, band, net posts or singles sticks except as provided in Appendix IV. " and Appendix IV: " [paragraphs 1, 2, and 3 talk about what kind of advertising is allowed. And then Paragraph 4...

    Weighting up the Crossguard of my Sword

    The problem with your proposal is that you are asking someone to describe the 'feeling'. Something that cannot be measured. I'm merely saying that _as far as established physics is concerned_ what you are stating is not correct. Now - if you are saying that adding mass to your racket in...

    Good LORD are commentators annoying...

    Tennis commentators must have gone to the same schools that stock market analysists went to. They always know what the right play was _after_ the point is over. Just like those analysists _always_ know what one was to buy or sell _after_ the market closed.
