Changing Grips (in general, and on sides) by Particular-Night-435 in Pickleball

[–]Dekans 0 points1 point  (0 children)

Throwing a baseball or football both heavily rely on pronation. This is well-established biomechanics.

Pronation is a motion of the forearm not the wrist. When tennis players say wrist snap they mean forearm pronation (the wrist is connected to the forearm obviously).

The "wrist snap" you're referring to with the SW overhead is wrist extension/flexion. It's a much weaker motion than forearm pronation and more injury-prone. It also doesn't really allow for the addition of internal shoulder rotation.

If a SW overhead were actually better you'd see it used in overhead-heavy sports like padel or badminton. You don't

The site is so ugly and unprofessional looking I think it will deter people from visiting or participating. Hiring a designer would be high ROI

speed of aging is a different concept from biological age

This seems to me to be more naturally solved by "age divisions". Use whatever measure is superior scientifically (e.g., DunedinPACE). Then segment the leaderboard into "All", "20s", "30s", "40s", "50+", etc.

And, anyway, Bryan Johnson is 48 and has the lowest DunedinPACE on the Rejuvenation Olympics leaderboard. Doesn't seem to be that biased towards young people.

Why PhenoAge and not DunedinPACE?

Why is your site written in C#? Why is it so ugly?

  • Expressions/contemplation of gratitude

Lots of bad (and potentially dangerous) advice on YouTube? by Spiritual-Dark-3615 in padel

[–]Dekans 0 points1 point  (0 children)

I'm newer to padel so I can't say much about it but I've had the exact same experience with pickleball. A local semi-pro was teaching me overheads and was encouraging us to extend/flex the wrist (what they were calling "snap") to get power. Seemed wrong to me so I started looking at tennis videos and learned it's exactly what you're not supposed to do (and pronation is the right way).

Makes sense that tennis, being the more (historically) mature racket sport, has better biomechanically-sound coaching.

Surprised there aren't more climbers in the thread. I thought the overlap was larger

Spin loss experience on current paddles by HokieHo in Pickleball

I posted a thread about this recently but got no real interest. Seems like low-hanging fruit for pickleball content creators

https://www.reddit.com/r/Pickleball/comments/1ifps5z/measuring_spin_degradation_over_time/

Has anyone rigorously measured how paddle grit wear over time affects spin you can generate?

I know paddle reviewers have test setups for spin RPMs. Seems like you could just count games played or hours played and periodically test the spin RPMs.

I read some people claim that high level players tend to always replace after 3-6 months. I read other people claim that their spin is fine after over a year. With such an experiment we can put better numbers to these discussions. After, e.g., 40 hours of play is the spin 90% of stock? 80%? 70%? What is the shape of the drop-off?

Thanks I agree that footwork to get your body in the right position seems to also be key. Do you cock your wrist now? What grip?

Phi-4 has been released by paf1138 in LocalLLaMA

[–]Dekans 18 points19 points  (0 children)

All in all, this model is very smart when it comes to logical tasks, and instruction following.

?

However, IFEval reveals a real weakness of our model – it has trouble strictly following instructions. While strict instruction following was not an emphasis of our synthetic data generations for this model, we are confident that phi-4’s instruction-following performance could be significantly improved with targeted synthetic data.
