I hear you, and if you look at my methodology, I actually took those factors into account and controlled for them as best I could. I started off by giving men a 5-to-1 starting advantage based on Alexa statistics for the demographics of Steemit as a whole. I also looked at two metrics--follower counts, and author rewards. While both of those things are of course impacted by Steem Power, I felt that author rewards would be the more valuable metric because it would have to come from user generated content.
