I'd appreciate any critical feedback to the following reasoning:
5Dimes pays +100 on 6-pt. NFL 2-team teasers, implying a break-even win pct. of 70.7% on each leg.
They pay +600 on 6-pt. NFL 2-team pleasers, implying a BE win % of 37.8% on each leg.
Assume a non-integer spread, just so we can ignore pushes.
If you "tease" one team, and "please" their opponent, exactly one bet will hit, and one will miss.
Since 70.7% + 37.8% = 108.5%, we can say:
1) If teasers and pleasers have the same hold, that hold is 8.5%.
2) Either the teaser or the pleaser must have a hold of at least 8.5% in any game.
