Greetings Carlos!
And good luck with your new community! What is soccer?
Just kidding ;-)
There are many attempting to figure out ways to measure web communities economic value and rules that can be applied to insure success. Many doing web community development really want this to satisfy investors. I tend to prefer the truth myself

Here it is:
There is no standard ratio between pageviews or registered users and forum activity. Far too many factors go into community success and even the number of posts is not determinative.
What has been established is:
1. Online Communities which are an online version of an already existing real community are the surest bet
2. Moderated communities do substantiually better in providing value by just about any measure trhan unmoderated ones
3. Most participants are and will always be lurkers. Forums that respect their lurking members do better than those that ignore them ..or push their participation through posting
4. Good Site Navigation and Design, Quality Content in addition to forum, regular mailings and updates to members, a system for welcoming all who sign up and assigning a person to welcome them personally...are a few of many things a good community does to retain folks and grow.
And I do know Soccer ..football is another story I see it but can't figure out the joy of guys clobbering one another. Soccer seems more...errr..sporting to me !
