if bets gives you the true parlay odds, and it is always higher than the parlay odds offered by the books. why would anyone bet parlays instead of if bets?
for example at the greek:
2 teamer at -110 odds
parlay odds is +260
if you do the following with if bet:
bet 11 to win 10, if win/push bet 21 to win 19.09
if you win both leg of the if bet, you win 29.09, which gives you the payoff of +264 (true parlay odds).
this will give you the true parlay odds for 3,4,5,6,7, up to 15 teamers. imagine you get true parlay odds up to a 15 teamer.
the only limitation is the book limit, but i doubt anyone parlay a dime on a 3 teamer.
so why would anyone bet parlay anymore? (other than parlay a shitload of money to overcome the limit)
