    Erm, what's the point of this ?

    Everybody on the forum, and every shuttle manufacturer knows that choice of shuttle is temperature dependant.

    What confuses me with this ad. is that Yonex are using a 1 to 7 scale whereas most players/manufacturers relate to 76/77/78/79 or the 40's/50's speed scale. Why use another system to confuse people ???

    'Wow' indeed.

    maybe yonex thinks a 1,2,3,4,5 system is easier to remember than 74-80, or 40 to 50

    isn't it the responsiblity of IBF to decide on this, or Yonex thinks they are important enough so that everyone will follow them?

    I think Yonex probably wants to have a numbering system for both feathers and plastics.
    Anyway, the feathers numbering system used by Yonex may not be so accurate. For example I use Yonex AS-50 for testing/evaluation extensively for comparative purposes and I find their speed 2 is actually more suitable for a temperature of 25 degrees C, RH 50% and maybe a bit fast. The chart says differently and seems to be tailored to women or players who cannot hit well. I would rate the Yonex AS-50 as similar to speed 78.
