What's the point of having a time for the tournament if not everyone is expected to be on? The time to setup the matchups, arrange the matches, get the players (and judge) in a game. Play 2 (or 3) games, and then rinse and repeat. You then have to do this double elimination for EVERY person. That means at the very least, if you get beaten by both of your first opponents and they each win 2 games against you, you've fought 4 games.
Assuming each game takes a minimum of 4-6 minutes of time average (counting setting up the initial game and then playing both games) you are consuming 20-25 minutes of the tournament at a minimum. This is the best case scenario.
There's just no way this is going to be down in a time-efficient manner with 3-7 judges.
Edit:
Let's say you have 7 judges, they can judge 7 matches at a time. You have 32 initial matches to do, which means you have to wait for at least 5 rounds of judging. If each match takes 10 minutes (this is being lenient on time, considering each game has an 8 minute time limit) then the first round (WITH STILL NO ONE ELIMINATED) is going to take 50 minutes. No one else seems to realize this.
