In this video we show why we have rounded the percentages in the pre race download file to make it easier to filter the output uses ranges.
We have added in the Profit / Loss if Laying selections on Betfair at SP and we explain the difference between a DOB calculation and percentage drop.
Using an example of BFSP of 12.0. A horse would need to drop to 6.0 to DOB. However a true 50% reduction in odds from BFSP of 12.0 is worked out as (12-1)*((1-50%)/1)+1 giving 6.5.
For a horse with BFSP of 12 and an inplay low of 6.0 the odds reduction is calculated as (12-6)/(12-1)*100 giving a 54.54% reduction in odds
