    Swing Vision AI line calls and Analysis

    I have the above setting on the iPhone Tried with 'Automatic' as well. Still no go. I have windows 10 with NTFS file format. Whether I use Windoes Photo app, or just plain explorer - Windows PC does not seem to recognize there's a video file on the iPhone if that file is over 4GB. Could you...

    @Demented - if I may ask, what is that 'dead link' you got that formula from?

    Swing Vision AI line calls and Analysis

    @Dragan - when you say "(transfering video from iPhone to PC is almost equally easy)" - does it actually work for you all the time? I can indeed transfer most of the videos with no issues - but _any_ video over 4GB will not transfer from iPhone to a PC. Such video is not even detected by...

    Full kitchen remodel ahead...any advice?

    we remodeled our kitchen with stuff from Ikea. Cabinets + appliances. Only counter-top and backsplash were done by a contractor. It's been nothing but great. We were a bit hesitant at first as obviously those cabinets are not real wood - but they are holding for years with no issues. Plus...

    MTO's have to go!

    What needs to go in 'M' in MTO. Everyone knows that MTO are used any time one needs a break - whether it is medically related or not. So just make it official. You get X number of TO per set (or pay hour of a match), and you can use it as you want. If you use them up and actually do need a...

    I'm going to predict that Cressy will have a better tennis career than JJ Wolf. Discuss.

    Home made swingweight machine emulating Babolat RDC/Prince PTC - a fully working one. Total cost roughly $10...

    Very good observation on the torque vs angle dependency. I was thinking that perhaps because RDC-like mechanism uses two spring system that effect cancels out and therefore the oscillations are independent of the angle of the displacement. But that is probably not so after all.

    yes, agree, that's what I said as well true, as you say for a particular object. very nice! If I may ask - how do you accurately measure the amplitude? Now - as far as an error introduced by 'too large of an amplitude'. I think that does not actually apply for the devices like RD (or our...

    Home made swingweight machine emulating Babolat RDC/Prince PTC - a fully working one. Total cost roughly $10...

    yeah, yes, just poking a little fun at those folks that can tell 1point of a swing-weight difference by just swinging a racket. Although if I were to believe the conclusions of this paper "Measuring the inertial properties of a tennis racket" the claims that these RDC/Head/PTC machines are as...

    Lightest swingweight on ATP tour?

    Very good point! Although the fingernail on the pointing finger does not matter as it ends up being almost exactly at the 10cm mark from the butt-end - so it does not contribute to sw. But all the other fingernails - by all means...... :) Which is also why I meticulously shave hairs from my...

    Lightest swingweight on ATP tour?

    @Slowtwitcher - ok, since I'm equal opportunity bs calling. You actually liked @El_Yotamo posts in question (along with others), and you never called in question his physics/math explanation. You just argued that in practical sense the contribution of a grip to overall sw is zero. So you may...
