Assuming a whole number is a considered one

A total or spread sitting on a whole number allows a push, and its position often reflects where money balances rather than a precise estimate of the game.

The half point is bought and sold constantly; the whole number is where two opposing sets of opinion were made to meet. The refund built into it has a price, and that price is inside the odds beside it.

Whole numbers are not worse bets. They are different bets, with a third outcome, and the price should and usually does reflect that.

What follows from that is less comfortable. The push feels like a neutral event and is not — it is a bet that consumed time and capital and returned nothing, which is a cost even when it is not a loss.

What to do with it. Notice whether the number can push, and check the price against the half-point alternative before choosing.
