Using ATS records (O/U records as well) is rather fascinating subject that deserve to be discussed thoroughly. I was hoping to get it going here.
I do not use ATS history but I am wondering if I am missing something.
My take on this is that it can be of any use only if some other outside conditions exist. For example, if the linesmakers were motivated in any way to produce the lines that make as many teams as possible finishing season with ATS records as close as possible to 50/50 then fading would make sense. Is that their goal? I doubt but this is not impossible scenario.
If we do not make such farfetched assumptions then we should think that the linesmakers make the lines in a way that taking either side would be 50/50 proposition. The ATS records play no role here.
