I've observed one thing though.
The Reputation points also depend on your post count, unless someone else has contributed to it.
For example, my range of posts comes into 300s, so i have 4 reputation points.
Go4saket above has 5 since he has 400+posts.
The extra point is because you have the liberty here to add a point to your own account once & we dont waste that opportunity..
We've been around for a long time now, and this forum really rewards you for some good contribution(not sure about now though

)
Even if you dont get some high position, the satisfaction of solving other's problems is enough
