Stone and gold mine at one every 5 seconds (Or so I've counted)
You need 275 stone to make 55 steel
110 gold
Let's say that you get one gold for every other failed attempt:
220 attempts
so 495 x 5 = 2475
2475 / 60 = 41.25 minutes
Now for an orbital:
250 x 5 and 2 = 1250 and 500
Let's use the same gold mining theory:
1000 attempts
2250 x 5 = 11250
11250 / 60 = 187.5
Or 3 hours 7 minutes 30 seconds.
