[Menschenfresser]

ok. This ought to clear this up. I did a short test on an asteroid of medium size with the following stats:

143% mineral content
90% Organic content
127% radio content

First mined with a Lt. Cruiser having the following components:

Bridge, Life, Crew
Max Engines
One of each of the three miners at level one.

These are the results:
Mined 858 minerals, 540 organics, and 762 radioactives.
Maint. Cost on this ship was: 854 minerals, 29 organics, and 136 radioactives.

Then put another Lt. Cruiser on the same asteroid w/ three mineral miners (level one)

Mined 2574 minerals with a maintanence of 1004 minerals.

Gain of 1570...
