I think this needs to be changed.
Imagine in real golf if 4 players are tied at the end of the event. The commissioner says "this guy wins because he birdied hole 14 while you guys didn't... LOSERS!" Yeah I know that sounds so stupid it wouldn't even be a possibility of happening.
My suggestion is a mini tournament tiebreaker with a 12 hr clock. Play as many rounds needed until a real winner is established.
This probably isn't needed for ready-go's but it definitely is for the big tournaments.
