For the case I met in Starfighter, I am sure that was not caused by lag. Only one specify player (cheater) would jumping around in that match whenever I was going to lock him. Once he jumped out of my locking range. He would just stop his jump. As long as I reach him close enough for locking, he would just start jumping again. I understand I am just say nothing without any evidence. I will capture some video to prove if I meet that again shortly.
