I also don't like those odds for the first set, but I played in Maddog10's competition and won 2 times out of 3.
My second score was 4/5 and my third score was 2/5+1/14, with for the second game, I didn't want to post the right mb.
I did the calculation for costs and payouts.
One game: -1 * 1287 * 3.
Played 3 games.
Payouts: 0, 35100, 7821 USD.
