Chance of getting it by number of runs
0% 25% 50% 75% 100% 2 3 5 6 8 1 runs · 50% 1 runs · 50% 4 runs · 90% 4 runs · 90%

Each run has a 51.78% chance. The curve is 1−(1−p)ⁿ: there is never a guarantee, only growing confidence.

Farming assumes a radshare squad for relics and the planner’s per-mission timings (estimated/derived, labeled on each page). The foundry runs on its own: you can play meanwhile.
