As far as I understand, it's some kind of high-speed camera. Thus to record the highest speed, you need to be able to aim at the right place at the right moment, which is much harder in a real match.
Furthermore, in another thread I saw someone saying that usually the speed is measured later than what Yonex did this time. So no wonder TBH got a much higher number than FHF.

..thus 2 different scenarios, different conditions and set-ups.

FHF' s smash was recorded by looking at the first 15cms or so of shuttle flight after being stuck by the racket.
TBH's smash was recorded by looking at only the first 3 cms of shuttle flight after being struck by the racket - the moment of maximum speed only !!!!!
No wonder TBH's figure was much higher !!!!!! It didn't take into account the significant deceleration affecting the shuttle over the longer distance in the case of FHF .
Oh so sneaky Yonex. Great marketing though.
Unfortunately, most people on this forum are ignoring the simple fact that the system used when measuring the Arc ZS smashes is fundementally flawed and designed to deceive. People just WANT to believe desperately that this racket is the new messiah so they turn a blind eye to the simple facts.

Another yonex style to impress people ... I wonder if Malaysia Boleh!! Yonex Boleh?? I hate their style, but I love their product but not the price . But yes , Li Ning have much ridicilous price!!!Junior brand(in badminton) but more ridicilous price then yonex . Im not confidence with Li Ning technology myself , but they dont do any market strategy(yet?) like yonex are doing/having right now ~~~

Is there a math professor or............nerd..

It is the slower speed recordings that weren't conduct in the same way as TBH test. Tests should be done in consistent manner with each others or else they shouldn't be used for direct comparison with each other
personally, i much rather have 1/2 of that 421 kpm and landing the shuttle at strategic position, like inches from the line or hard to reach spot around your opponent's body

So, just a minute, which came first ? The chicken or the egg ?
Recording the maximum speed (over 3 cms) IS flawed when the norm is to measure over a longer distance. It was simply done the SECOND way to deceive and to sell more rackets.
Yes, tests should be done in a consistant way - so why did Yonex 'move the goal-posts' so to speak, from the known, general way of measurement ??
I don't think I have to answer that one.
As to the relative merits of a hard smash, I agree with you totally. As I have said before, smashing is just one of many facets of our great game - and one of the least important.

As I said, such "speed measuring" is kind of meaningless unless we measure everything in exactly the same situation.
But I don't think it's fair to call the Yonex measurement "flawed". How come measuring speed at 15cm is OK but at 3cm is not? If FHF can have his smash measured at 0.01cm and get 600km/h, do it. It's good for badminton. I don't see any reason why such measurement should be criticized.
10-23-2009, 05:28 PM #48
As long as Yonex mention the "3cm", I don't see anything wrong with hyping 421km/h.
The technology of measuring speed is evolving. As I said, in 1997 DJ's smash is measured at 199km/h. Around the same time Simon Archer's smash (I have the impression that it's not in a match, correct me if I am wrong) is measured at 260km/h. Those measurement must be taken over an even longer distance than 15cm. So should we go back to those very old ones? Of course not.

The technology of measuring speed is 'changing' - and for marketing purposes only. Why change, if not to deceive ?
Maybe car performance should be measured over 0 to 6 mph rather than 0 to 60 mph ???????
Re. earlier speed records, sorry but 2 wrongs don't make a right.

Hmm.....Why can't they do a record in a professional game? If they have all that time making marketing schemes, go invent a Eagle-Eye for badminton! Geez~!
