I have a spreadsheet that calculates Moneylines for Over/Under bets increments of 0.5. There is a table starting at 0.0 and goes up by 0.5 for each line of the table and gives an estimated winning percentage and fair moneyline for each line. Then on the side there is a section where you put in the "expected total" and put in your desired EV or edge, once you've put in those details it completes the necessary calculations.
My question is this:
If I am betting a line with an Asian Handicap in Soccer of Over/Under 2.5 and 3 Goals, effectively a Over/Under 2.75 Line, how would I use the Poisson Table to get the Fair Moneyline price for this outcome?
I tried to make a new Poisson Table that went up in increments of 0.25 instead of 0.5. However, this just yielded the same Fair Moneyline price as the Over/Under 2.5 Line. That is because the spreadsheet doesn't recognise that the 2.75 Line represents half your stake on the 2.5 Line and half your stake on the 3.0 Line.
Would I simply take the Fair Moneyline for Over/Under 2.5, the Fair Moneyline for Over/Under 3, convert the American odds to Decimal Odds, add them together and divide the odds by 2 to get an average odds? Would this method give me the Fair Moneyline price for an Over/Under 2.75 Asian Handicap Line in Soccer? Or would I need to use another method to determine the Fair Moneyline price for this event?
Any insight into this subject would be much appreciated, thanks.
