This would be a good statistical test if someone can compare e.g. average racket + shuttle speed with head heavy racket, and then compare with head light racket.
Those equations say that for head heavy racket with approximated mass at 40g, and a head light racket with approximated weight at 35g, the head light racket need only be swung 1.05% faster!
I'm pretty sure that if we got a large enough sample, we would disprove this!

Vr2 = Vr1*Mr1/Mr2*(Mr2+Ms)/(Mr1+Ms)
Mr2 = Mr1*Vr1/Vr2*(Mr2+Ms)/(Mr1+Ms)
Plugging in those example wts give 1.59% difference in swing speeds, not 1.05%. Not much difference, but still... something somehow doesn't add up.

Also another thought, since craig and Notorious have brought up shaft flex and matching biomechanics:
do any of you play golf?
I ask because I don't but I've seen and heard how the pros have their clubs customized with respect to shaft flex, swing wt, angle, length, etc according to the player's swing profile.
Would be interesting for someone to do that for badminton. I would be the first to sign up.

I don't think it would work in badminton though because imagine all "those" folk that use 28lb+ tension Voltric z force's or MX 80's After analyze the swing you have to tell them you need to use a 21lb flexi racket with an enlarged sweet spot or be better off with a Yonex mp2 junior.

1.0158... is 1.016 is 1.02. If you want to do rounding or lazy ok as 1.01 but DON'T calculate it as 1.05
one step at a time and check your math specially when you are sticking with your point. Specially taking deep dive in complex equations

folks can use
basic, Bevel, Panhandle or any other damn grip based on situations ...
By the way it's really cracking me up abt how collective wisdom is progressing on this thread and ultimately coming to same scientific discovery inclination which was made in other threads like with lighter rackets which giver faster swing speed and more wrists game style option panhandle could become more acceptable as compare to last 30-40 years.
please continue .. The more scientific discovery you will do more you will realize the EVOlUTION is already underway
since this thread started becoz of that 'unusual' thread it wld be more ironic the further you will fine tune this thread the more it will support the original thread topic of lighter rackets and grip styles allowed to optimize benefit in terms of Time, Power, Control integration parameters

actually I wont bother

Check this vid out, this is the product of evolution.
This ain't gonna get done with a pan handle grip. Pronation/supination is key to being able to swing faster.
But please try to proof this wrong along with the other panhandle theory stuff.
Due to the nature of this thread though and to forward what I have read from you before, I want tracker results and inputted figures to formula's as the only acceptable propositions.

No way a panhandle can match a full pronation. A panhandle grip will only allow wrist movement of 1/2pi radians maximum (90degrees) but a full pronation allows you to accelerate the racquet over more than pi radians (180 degrees) so your angular acceleration can accelerate the racquet over more than twice the distance so you can get a much greater speed with pronation that with panhandle. Your muscle in the wrist used for panhandle would need to be more than twice as strong and the rest of your wrist muscles, ur fingers, ur arm and most of your shoulder combined to achieve the same head speed and momentum so there is no way a pan handle grip is close to as powerful no matter what some people think. Also, the rapid deceleration on the follow through of the pan handle shots will actually tear the sarcomeres and connective tissue in your muscles apart and cause small rips in your tendons which can take over 8 weeks to heal and may never heal properly or fully if done repeatedly not to mention the pressure your nerves come under from the stretch in complementary muscle which actually squashes and stretches the nerve at the elbow causing irreparable nervous damage if done too vigorously. I cannot stress how bad smashing with a panhandle grip is for your forearm muscles and it has no power or accuracy gain. Pan handle belongs for drives and net kills. Shots requiring more power than those will just damage your wrists and arms and eventually make you incapable of playing. Pronation is more powerful, more deceptive, more accurate, easier to recover from and causes far fewer injuries with proper technique. Just so you know.

Please no panhandling talk on this thread... save it for the other one... :P

If you notice Power smash does NOT win rally. It's catching your opponent "before he / she recover" to take the shuttle and passing before that recovery wins the point. Naturally at advanced level it's Power Smash which does that and hence people relate More Power smash means better chance of winning rally and hence Power (hence Pronation).
But if you want to to "Apple to Apple" comparison than consider the "trade-off of Power Loss ? against TIME gain".
In a given TH example in (craigandy) .. TH hit that shot as 305Kmph (hitting speed) which caused oppoenent "no chance of recovery by the time his racket in the path of shuttle trajectory" where shuttle already passed him on ground (that split second difference caused by Power 305KMph smash speed).
Now assume it's Panhandle shot. Let's say Power is less but TIME is gained for hitting early (Hitting early is the characteristic of Panhandle grip) . .say by 0.1 second.
So whatever equation these guys are figureing with basic grip and time taken from racket hit to pass the opponent at say 200 km (normal Power smash speed at advanced level) .. add 0.1 second for panhandle grip hit and even probably 120 kmph could give you same effect to catch opponent before he/she recovers.
Also Pronation could be done in Panhandle (not in full effect but 50-75% of basic grip). Panhandle grip (like others is at wrist / finger level) but your elbow .. you can do the pronation of Elbow (50-75% if not 100% of basic grip hit style).
So on BOTTOM LINE effect of hittign before opponent is recovered is managed.
I am sure few genius guys here with frame by frame ability can measure a time on basic hit .. add 0.1 second (assuming it's panhandle grip hit) and figure out how much "equivalent less speed" is needed for same BOTTOM LINE effect.

@Superzoom Again only formulas, tracker vids, etc to prove this panhandle stuff not semantics, not for this thread. Sure everyone will be happy to look at your findings in this thread if you do that. Real figures though.
