Normally you get a low upstream when your far away from the box, do you have an attenuator on your hub

I'm sure JB has made a slip of the finger here. When you are far away from the street box, attenuation back to the box is higher and more power is require to overcome this attenuation.
When you are close to the box, then if everything else in the circuit is the same, the upstream power will be lower.
Thing to note though is that upstream power is commanded from the VM end (the CMTS). If the CMTS can't understand what it receives, it commands your modem to increase power until it can understand what the CMTS receives.
That being so, only 30 dBmv of power is required in your case. Quite OK.
