Please explain to me how:
You can take a house theo 5% or much higher hold ( Example Masters to win bets)
Yet magically post the "NO"s on it and suddenly argue the vig on those is no longer like 20% but suddenly below 5%!!
You're really confusing apples and oranges. One bet is a
2 way YES/NO prop and the other reference is a future bet pool of
many, many options, two different pools.
In fact, Circa occasionally has different lines for its YES in the YES ONLY pool than the YES in its YES/NO pool! And I agree the line is generally made using the YES side simply because its much easier to estimate.
To sum up: In the larger pool, you are stating the overall theoretical hold %, while the single YES/NO bet has an entirely different hold %.
