Blue numbers? I see them as green if I understand you

I actually didn't check the rate of increase against what was stated in the box next to the total amount. might do that later

I did see that a orbital refinery will produce 25 resources for every 100 units a cargo ship returns with and even though there was enough extracters to account for all 12 ships it produces they will move out of the system.
I've yet to check if this is the same ratio for tech upgrades and normal and hard games.

The reason i was checking this out was that in one game i put one in every system i owned and couldn't work out why all the ship sat around going no where.
