if you start in upper round 1 its better for you to lose first match, then win the second match in lower round 1 - congrats, youre qualified to tokyo, in only 2 games
but if you win the first match and then proceed to lose to the top seeded team in upper semifinals, then lose again, you are out, which looks like 1W-1L-1L. so you go 1w -2L in 3 games. you will therefore have to go 1W-1L-1W (2W-1L) in this scenario to qualify.
