    To test the speed of a shuttle. Use a full underhand stroke from the back boundary line, a shuttle with correct speed will land between the the two markers you are referring to.

    Okay....but two humans with varying "full underhand stroke" for same shuttle will give different results...how does one account for that?

    Even the same person will hit it differently each time.

    That's why there are two markers. :)

    Your next thought will say that it is very imprecise..... And you would be absolutely correct. :D

    Should be in the rules of the game published by BWF.

    I wouldn't be able to give the exact reference.

    it is from the 2016 edition of the rulles but still the same(link at the end)

    edit: looks like the rules gets reviews every 4 year.

    3. TESTING A SHUTTLE FOR SPEED
    3.1 To test a shuttle, a player shall use a full underhand stroke which makes contact with the shuttle over the back boundary line. The shuttle shall be hit at an upward angle and in a direction parallel to the side lines.
    3.2 A shuttle of correct speed will land not less than 530 mm and not more than 990 mm short of the other back boundary line as in

    Diagram B.
