How it works
A middle is two bets on opposite sides at different numbers, say Over 47 at one book and Under 49.5 at another. If the result lands in the gap, both win. If it misses you lose a little to the vig. The Antic Middles tool finds the gaps; this calculator tells you if the window is wide enough to be worth it.
Example
−110 on both legs with $110 on each: a miss costs $10.00 and a hit wins $200.00, so the gap has to land 4.76% of the time to break even.
