How many counters are in the usa?

Assuming, that counters are clever people and also using the internet,
I think there are no more than 500 people in the usa, who are practizing cc.more than 10 hours a week. I have just taken a look at the number of views on this site. They show about 50 to 200 views/post. Another conclusion could be, that from these 500 skilled players only 5% have the bankroll, to bet a maximum of 500-1000$ at a TC>4(Hi/Lo). So that�s 25 people. Is this a threat for the casinos? Off course not. Are the other 475 people, betting 5$-160$ a threat? Off course not. Who has any comments?

Thank you for any input.
