no they arent.
those numbers are total prize money, not prize money per round.
- Playoff champions: $1 million
- Playoff runners-up: $200,000
- Playoff semifinal losers: $100,000
- Playoff quarterfinal losers: $50,000
So look at it another way....
If you make the playoffs (quarterfinal) you are guaranteed $50k
If you win your quarterfinal match, you get another $50k ($100k total)
If you win your semi final match you get another $100k (So guaranteed $200k)
And if you win the final you get a further $800k (total 1m)
So a losing semifinalist could have had 4 fights (2 league fights, 2 knockout fights), and for that will get about $120-140k total
its not $50k + $100k + $200k
