Do you get the point for that last round bye if you leave before completed?
Bye in the last round

Strangely, I was recently in a tournament where, beginning with Round #2 through Round #5, there were 3 players, but only 2 out of the 3 would play, with the 3rd having a bye ... so, since the 2 players are chosen randomly (I guess), 1 of the players has had the last 2 rounds off while another 1 has played in every single round. There are only 2 left for Round #6 ... hopefully it'll end soon.
If that made no sense to you, the reader, imagine what it has done to the players!
If you get a bye in the last round of the tournament you should be able to
leave and start other games
