Editing Vigorish (section)

== Proportionality ==

It is simplest to assume that vigorish is factored in proportionally to the true odds, although this need not be the case. Under '''''proportional vigorish''''', a "fair odds" betting line of 2.00/2.00{{efn-la|Betting lines offered as examples below represent the ratio of total payout (stake + winnings) to the original amount risked. In the case of a $1 wager, a [[Fixed-odds gambling|fixed-odds]] betting line of 1.8{{overline|3}}/2.20 would result in actual winnings of $0.83 and $1.20 for the backers of the respective outcomes, once the original $1 spent to place the wager is subtracted. The amounts and currency used are irrelevant; the calculation is always: a wager of size {{mvar|n}} offers a total payout of {{mvar|n}} × the betting line.}} without vigorish would decrease the payouts of all outcomes equally, perhaps to 1.95/1.95, once it was added. More commonly though, '''''disproportional vigorish''''' will be applied as part of the efforts to keep the amounts wagered balanced, such as 1.{{overline|90}}/2.00, making the outcome with fewer dollars wagered appear more attractive due to the larger payout.
