I'm an amateur and I don't know all the rules in Badminton.
I was serving the backhand low service. Now someone told me that I have to hit the shuttle after I have fully release it.
I debated with him that is totally impossible to serve if I have not fully released the shuttle.
Again he told me that I'm releasing the shuttle at the last moment, not giving enough time to release the shuttle entirely.
Now I want to know:
Is there any rule that says that I have to give minimum x amount of time to release the shuttle entirely before serving?
Or what is the minimum time to serve after realising the shuttle?
I was practicing it like told in the Youtube tutorial and I'm pretty sure I was doing as much possible exactly like that.
