Formulas
Notation
a = odds at (mid − 0.5) b = odds at (mid + 0.5) S = total stake
xa = stake on (mid − 0.5) xb = stake on (mid + 0.5) xa + xb = S
Synthetic odds — Over (push at total = mid)
Over (mid − 0.25) = (a + 1 + b·(a − 1)/a) / 2
Over (mid) = ((a − 1)·b + a) / a
Over (mid + 0.25) = (1 + b + b·(a − 1)/a) / 2
Synthetic odds — Under (push at total = mid)
Under (mid − 0.25) = (a + 1 + a·(b − 1)/b) / 2
Under (mid) = ((b − 1)·a + b) / b
Under (mid + 0.25) = (1 + b + a·(b − 1)/b) / 2
Stake split — Over
mid − 0.25 : xa = S·(a + 1)/(2a) · xb = S·(a − 1)/(2a)
mid (push) : xa = S/a · xb = S·(a − 1)/a
mid + 0.25 : xa = S/(2a) · xb = S·(2a − 1)/(2a)
Stake split — Under
mid − 0.25 : xa = S·(2b − 1)/(2b) · xb = S/(2b)
mid (push) : xa = S·(b − 1)/b · xb = S/b
mid + 0.25 : xa = S·(b − 1)/(2b) · xb = S·(b + 1)/(2b)
Converts two adjacent Asian Handicap or Goals half-lines into equivalent synthetic whole-line or quarter-line markets. The calculator also determines the correct stake split needed to recreate each market, making it useful for pricing markets with push outcomes or comparing bookmaker and Betfair Exchange prices.
