That's how our rep system is set up. If I rep you, you get +5 rep points than say someone with no rep(+0) or when someone has little rep power(+2). I know Trey B. has a higher rep power than me. The more you rep, and the more rep that is given to you, will make your rep power go higher.
I a Mod at a forum that uses the rep system and it is set up so you can see what other rep points are right under their post count. Also, when you rep someone positive or negative it auto notates your name. That helps stop these people who neg rep you just because you can;t see their name
