Hi,
with the attached correct score screenshot bet1.png, where 4.00 is to be put at 7.80 for 1-0, the what-if shows 25.84, and 4.00x(7.80-1)x0.95=25.84, looks correct.
but then with screenshot bet2.png, 10.00 is to be put at 6.20 for 2-0, and the what-if shows -4.00 becoming 45.60. But ought it not be -4.00+10x(6.20-1)x0.95=45.40, there seem's a discrepancy of +0.20.
then with bet3.png, 3.00 is to be put at 60.00 for 1-2, the what-if shows -14.00 becomes 154.85, but oughtn't it be -14.00+3.00x(60.00-1)x0.95=154.15, there seems a discrepancy of 0.70.
this 3rd screenshot is at 13:41:52, if I clear bets and rebet 3.00 at 60.00 for 1-2 as with bet3.png to get the 4th screenshot rebet.png, the what-if shows 168.15, and 3.00x(60.00-1)x.95=168.15 and it seems correct.
so have I misunderstood how betfair calculates profits for correct score, or is there a bug?
thanks for any help
Richard
