I am glad I am not the only geeky fan girl. About 2 months a go a friend first got me really hooked to a show I only watched casually - so I made my first investigation of the fan boards only to find on the Sam/Dean battle in process on most of the boards I checked. Since after a my first marthon viewing I really thought Dean had the majority of the story but before I posted like you I went and did a count. My numbers are slightly different since my criteria was different (screen time) but like you I found that the balance even and the numbers were was with in minutes with Sam being in the lead in season 1 by 1 episode, Dean leading season 2 with 1 episode and season 3 was an even split at 5 and 5 when I did my count. So it is really all perception

Thanks for the great write up

Zaz - highly amused by it all
