while i am not having much luck here with all this apathy, maybe somebody can tell me whose line scoresandodds uses? I just realized that their history blurb showing recent line movements (like 23/22.5/21) is actually a link and if you click on it you can see the date and time of the line change. it is actually quite interesting and i am considering writing a scraper to collect that historical data and maybe build a model that looks at the line movements and what the correlation is to the outcome. over the years i have read a lot about 'steam' players (and their getting restricted for playing steam) but i have never seen an empirical study. anyone interested can respond here or by PM.
