    LD90 is low cost racket from Li-Ning.
    Quality and racket's specs of It is different from N90 and N90LD (or N90ii N90iiLD ...).

    Weights are extremely difficult to get down to the last gram. 83-89g has a weight 6 grams, which is a +/- of 3g. Which in reality is only 3.5% error margin. when put in percentage, the variation really isn't large at all.

    well, if I'm going to choose a 3U racket I don't want my racket to be 83g. we are talking about racket here. The variation is too big.

    The following are the weight classes for yonex:
    4U (80.0-84.9 g)
    3U (85.0-89.9 g)
    2U (90.0-94.9 g)

    Following the same calculations, even the highest quality of yonex rackets have a 3% variation.
    If you can legitimately feel the difference between less than 2.5g on a racket that weighs 80g+, then good job, that's some extraordinary super power you have there.
    In reality, i'm sure some people are familiar with what a "bell curve" is. Which is how I would believe most manufacturers would make their rackets. most rackets will be 82.5g for a 4U weight, and smaller quantities would be close to 80g and 84.9g. E.g. 100 rackets made, 70 would be 82.5g, 20 would be either 81 or 84g, and only 10 rackets would actually fall on the 80g/84.9g variation.
    This of course is only speculation and how I think the quality check is done, major brands just simply cannot have too many rackets that fall between weights classes. Lastly, this doesn't even factor in the grips and strings we use, by then, the weight variation is even less significant.
