ATR Formscan Index

[robert99]

Anyone know how the ATR (at the races) Index data is arrived at? For example, Carlisle 16:10 Sunday Zelos Diktator ATR Index 88.77, 11.11% match value, 799.01 full total Jeronimo Joe ATR Index -88.77, 11.11% match value, -799.01 full total

Re: ATR Formscan Index No idea mate..........I've looked at it and it seems pretty impenetrable. From what I gather it just takes into account runs of the horses against other horses in the race From the example you give I'd say as those two horses are a mirror image of each other than they must have run against each other but not against any other horse in the race. But the sums are double dutch to me............
