Once you have complied your Grade figures, you will make a discovery that the MPS figures for grades at different tracks over different distances will vary, the shorter the distance the higher the MPS figure, by using the Linear regression formula the same way its applied to Horses, you can find the deceleration rate and make adjustments to those Base figures..ie because in your sample of 20,000 lines you will have different numbers dogs competing over 450 or 525 metres you will need to avg the distances for each grade and make the relative adjustment.
