Once you have saved the spreadsheet onto your computer you should open it and enter your required "payout" and "markup" into the spreadsheet in cells E4 and G4. The back and lay odds will then be automatically generated together with the appropriate stake for each individual bet in each market. Note that you will need to do this for both the Premiership and Championship sheets (you can switch between the sheets by clicking on the appropriate tab at the bottom of the sheets)

You should then compare the generated odds with those available with the bookmakers and on the betting exchanges for each market and place your bets accordingly. For instance suppose the spreadsheet generated back odds of 2.68 and lay odds of 2.44 for a home team and the team was available on Betfair to back at 2.72 then this would be a potential bet (to back). However if the home team was only 2.36 to back but 2.38 to lay then this would now be a potential lay.

Lets take another example. Say the spreadsheet generated back and lay odds of 3.47 and 2.87 on the Bookings market for '"25 points and under". If the current available odds on Betfair were 2.78 to back and 2.84 to lay then the lay would now be a potential bet.

Even if the current odds available do not allow a potential bet you can still put your bets up anyway (back and lay) in case the market moves and one of your bets gets matched. Of course if the market moves both ways over a period of time and both your bets get matched (back and lay) then you would make a guaranteed profit whatever the outcome.
