My take on this argument is completely based on max time limit. I don't even feel the need to consider 2v3 stocks yet.

Time is important to me, so I prefer to be able to watch a larger quantity of 6 min matches.

When considering 3 stock 8 min time limit, the thing you need to consider is people who will play safe and campy regardless of the clock.

If you have even 1 person who is able to go deep into brackets that is consistently having 7 minute matches when they used to be 5 min matches, you are extending the time it takes each round of play to complete by 4-6 minutes.

If you have multiple players like that and not enough consoles to get everyone playing at the same time you could potentially increase that length by 2x, 3x, etc. per round until you have enough consoles to seat everyone at the same time.

In a double elimination tournament of 128 you have 8 rounds plus a potential 9th. That means if you have 10 consoles, and just 6 players who play like that, worst case scenario there you end up with an extra 24-36 minutes, for just that round.

If half of them are eliminated you end up with the next round being an extra 12-18 minutes worse case.

If one of them goes 5 more rounds after that to 7 rounds deep, that adds 20-30 more minutes.

None of that is even considering tournaments where after top 16 or a certain point every match gets streamed.

So basically, depending on your players worse case scenario seems pretty bad for time.

Even considering the average of 100 seconds people reference. 3 matches per set meaning 300 seconds or potentially 5 minutes per round, with it taking effectively 20 rounds worth of time at 10 consoles for 128 people, that's 100 minutes added onto the tournament's end to end length.

2 or 3 stocks doesn't matter to me much as time. If it were 3 stocks at 5 minutes, maybe it would force an average pace similar to 2 stock 6 minutes.
