Can someone pls explain this?. Recently I came across a new place where I played, I notice some marking on the rear r/h side of the court were we are playing. There are two marking located one before the double serving inside rear line and one after the double long serving line.Both are marked on the single inside line.There is no marking on the l/h side. I try to ask some older player , they say they also do not know what the marking for? I hope you all know what I am trying to ask as I have no photo to post. Thank you.
check this out. it is used to test shuttle speed. ideally the shuttlecock should land between the markers. http://www.badmintoncentral.com/badminton-central/content/view/82/56/1/2/
