You're wondering when to stop your tech-mining when ruins become literally unattainable. The usual go-to tip is 14 months or on average 2 cycles, but who has time to keep track of that? Better Colonies (http://fractalsoftworks.com/forum/index.php?topic=17103) has a tracker on tech-mining so whenever you hover over the industry you know to disband them or not.
Well, you should never stop during your first month obviously because in THIS easy to read table, I'll help you out.
Vast Ruins are base ruins. The default amount and rate that you should be getting in a month. The bold is important, take note!
Extensive Ruins yield only 60% of a typical Vast Ruin's month.
Widespread Ruins yield only 35% of a typical Vast Ruin's month.
Scattered Ruins yield only 20% of a typical Vast Ruin's month.
On the first month, the ruins are untapped and yield out 10x of their usual drops while yielding like a vast ruin regardless of ruin type. Let's suppose you're the type of guy who wants to tech-mine everything to the bitter source. Now when should you stop tech-mining, the information is up to you when you feel the odds do not balance out the upkeep.
| Months | Scattered | Widespread | Extensive | Vast |
| 1st | 100%-140% | 175%-245% | 300%-420% | 500%-700% |
| 2nd | 18% | 31% | 54% | 90% |
| 14th | 9% | 17% | 29% | 48% |
| 27th | 5% | 8% | 15% | 25% |
| 59th | 0% | 1% | 3% | 5% |
| 70th | 0% | 0% | 1% | 2% |
| 80th | 0% | 0% | 0% | 1% |
| 90th | 0% | 0% | 0% | 0% |
Wait, what if I don't want to EVER stop tech-mining?
