My stats are counting more visits that im actually getting

According to my 'recent visitor activity'. Why is that? It's making me think my site is more popular than it is! Please help :) Thanks so much!
In Summary stats "visitors" will appear overstated when visitors' browsers don't accept and keep cookies., because every pageload will get recorded as a new visitor. In detailed stats such as "recent visitor activity" visits are grouped by IP.
Your best choice is to look at "pageloads" in summary stats and "recent pageloads" in detailed stats.
