Hello all, I have been playing and watching badminton for a number of years and have grown very frustrated with inconsistent calls by service judges. I believe I come up with a possible solution. Get the tallest badminton player out there and measure the height of his waist. Voila! That is now the maximum height that ALL badminton players can serve at. Get an apparatus for the service judge that consists of 2 parallel bars at a distance from each other, perpendicular to the service judge's line of sight. The bars are calibrated to the aforementioned maximum height. Then make the service judge sit at or adjust himself so that his eye level allows the 2 parallel bars to line up with each other. That way, the service judge can clearly see whether the shuttle is struck above or below this line that ALL badminton players must adhere to. Tall guys don't get an advantage and short guys aren't at a disadvantage. Lastly, have a high speed camera calibrated at the same height so service calls can be challenged. There are too many bad calls, missed calls etc. that really ruin the game. That one service judge, Fritz whatever, is particularly bad for this. I hope the BWF does something about this problem soon.
