There's roughly 500 Premium members, not including any Mods who've bought it, and 177,853 registered users.
This makes it around 0.3% of GTP that's Premo.
Although my mathematics could be way off.
Edit: And 96% of GTPlanet users are called Alex.
We can see through the interior of the Premium users?
A negligee?
Wait, what?
Members with their last post between today and January 8th, 2011 and more than 30 total posts - 5,679.
Now we just divide the number of Premium users by that number to get our answer. Which is about 9.4 percent. So approximately the ratio is for every 10 standard users, there is 1 premium user. Only counting active users. Definition defined in previous posts.
We should set a threshold of activity and define who is active from there. Like less than 0.5 posts per day.
Agreed. Out of the 100,000 members, it seems like half made a few posts and never came back. Could we define an Active user as a person who's post per day average is 0.5 or higher and has posted within the last two months? I wonder if there is a filter in the members list section we could use to answer this, so the ratio would be as accurate as possible.
