If you enter into your spreadsheet (ART- avg of all runs)/ stand deviation will produce a z score you may decide you don't want to include in your calculations any run that scores more then 1.00.
example
1 form line time = 19.807
average all runs = 19.722
stdevp .313
(19.807-19.722)/.313 = .271
this run is kept in your calculations.
Your better to look at a formline based on a z score I feel

I actually undertsand that.
One question, do you eliminate ALL outliers, be they too fast, or too slow? Or is there a case to consider a dog's very best ratings in the greater scheme of things, and just eliminate the slow outliers? |
