Reading through @iacas posts I openly change my opinion to he’s definitely not biased.
I don’t see how it’s possible to have further distance with the JV swing, and I doubt he or anyone made any such claims. With testing I suspect you won’t see any measurable distance lost. By measurable I mean you’ll notice it on the course.
I say this because I and many others who’ve tried the swing haven’t noticed any distance lost. If you’re making claims otherwise then I suspect (not proven) you’re missing a variable in an extremely complex equation. It’s also possible you’re not missing a variable and the explanation of no distance lost is purely from a non-optimal traditional swing.
It would be nice to have an explanation for all the JV swing distance anecdotes, but we lack data and nobody is willing to run the tests, even including JV himself.
I finally broke 100 for the first time since picking up golf in May 2019. This was at a Par 72 golf course in Barboursville, WV (Esquire Golf Course). My focus during this round was to hit all shots with a smooth tempo using a "tick tock" swing cue. Sounds dumb when your out there saying it out loud lol but I've never been more consistent. My final score on the course was 90.
I takes a lot of work to correct swing issues. Many of us have played with physical limitations. I am better now, but have played through shoulder and knee injuries that required surgery. They weren't caused by golf. @billchao played with me on my last round in 2018 where my knee just stopped working.
Changes can be made though and no one is beyond hope. I could be as simple as just shortening your backswing, which is less limiting and produces better contact. I really encourage you to post a video in the Member Swings section and let us help.
Not sure how much has changed, but I had the opportunity to take the Pelz 2 day, chipping, pitching, putting, and bunker clinic, back in the early 90's (maybe the late 80's). It was great. I'd say go for it.
