well i'm trying to do the math on it, but don't have that level of analysis in my being
It's obvious to me that -110 you must win 53% to profit slightly, +100 only 50.01% and -120 54.6%
What i struggle to work out is with 0.5 +105 vs 0.75 -120
How worth it is it to lose by a single goal and only lose 1/2 of your stake (i am betting everything risk 1.1x to win XXX in this sport) vs losing your full stake on a single goal loss? Winning 1.1x *1.05 = 1.16x when you win vs 1.1x *1/1.2 = 0.92x
Scenarios
| 0.75 | 0.5 |
NED 2-0 | -1.1 | -1.1 |
NED 1-0 | -0.55 | -1.1 |
0-0 | 0.92 | 1.16 |
So you're trading 0.55x on a single-goal loss for 0.24x less when you win. This goes against my thesis of making bets on coinflips at or above even money and trying to pick up those pennies on each transaction thus being +EV over time, but it seems to make sense even despite the higher required win rate to be profitable
