Is there a quick way to calculate the payout for place numbers on payouts of 7:6, 7:5 and 9:5 without having to calculate it all by dividing by 5 or 6 and multiplying by 7 or 9? Or is it just a case of familiarity with the bet size? Sometimes i will hava an irregular amount up where i do not know the payout as a result of repetition and i don't really want to work it out in my head when i'm shooting. Eg, i know quickly what a $240 6/8 pays but not so quickly what a $265 5/9 pays. For a payout of 9.5 / 1 on a $75 hard 6/8 i know quickly to multiply by 10 and minus half the wager, so the payout will be $750 - $37.50 = $712.50 plus the bet stands. I was looking for similar short cut calculations on some of the other payouts if anyone knows of any.
