We are currently in the process of trying to do an analysis of unique user counts utilizing the MAP Toolkit for our SharePoint 2010 environment. To try and determine how accurately the tool is determining the user count we pointed the MAP Toolkit and WebTrends to the exact same log files. We are noticing that WebTrends is picking up more users. Is this because the Toolkit is not counting 300(s) based errors for users. These were a couple of entries where we noticed that WebTrends was counting users as unique, but MAP Toolkit was not.
