But is it juking the stats or adding another stat? Post fix it seems to me that he has 3 numbers, the number of people who loaded them page, the number who spent enough time to read the first 'graph, and the number engaged enough to move into the archives…* Pre fix, he only had the first and last numbers. Personally I'd be tempted to use the page visibility API, and a number of timers, and really track who's reading 1 'graph or 3 or the whole article. But I sure don't think collecting more data, is juking the stats. * Although this last number doesn’t seem to be accessible except via your vistor flow page. (Or I couldn’t find it)
