Since Piwik tracks “number of unique visitors”, there is an algorithm somewhere which decides whether a visitor is a new visitor or is just a returning (and thus non-unique) visitor. My question is: where is this algorithm located? My goal is to modify the algorithm such that I can change how Piwik categorizes unique visitors. Any information about how/where Piwik dumps this info into the database would be appreciated as well. Thanks for any information!
