1020 MC / 20 per run (I typically get 21, sometimes 24, occasionally 18 but for simplicity's sake we say 20) = 51 runs - 1 for previous maps

50 runs x 12 stamina = 600 stamina = 25 days (so obviously, natural regeneration alone will not suffice)

THE FOLLOWING ASSUMES LEVEL 200+ SO YOU HAVE MAX OF 18 STAMINA

If we assume you ONLY use SC to refill stamina (and never charisma, since Stamina is the primary issue here):

To reduce 25 days to 7 requires a reduction of 18 days; conveniently, that's our max stamina, therefore you need 24 SC spent on Stamina to reduce it to one week (24 hours in a day x 18 days / 18 stamina per SC spent)

This is to get one copy of each TP unit at a rate of 20 MC per run, assuming no level ups (level up would take out 1 SC), IN THE FIRST WEEK!

If you're willing to go into Week 2, we can cut down our SC spending because we have 7 extra days. 168 extra hours/stamina / 18 stamina per SC = 9.333 SC saved, let's call it 9 so 15 SC spent in 2 weeks to get ONE copy of EVERY TP unit in 2 weeks.

Min-costing Aria and/or Echidna will depend on luck with the CR rolling.

Quoting myself so I don't have to repeat my original calculations of how many SC must be spent to get EVERYTHING (once).

If you take out Echidna and Aria (220 MC), you take out 11 runs x 12 stamina/run = 132 stamina / 18 per SC = 7.333 (round down to 7). Thus in 2 weeks, you can have Anya with only 8 SC spent if you're level 200 (and thus have 18 stamina max).

800 / 20 = 40 runs x 12 stamina = 480 stamina = 20 days. To cut it down to 14, you need to eliminate 6 days (144 hours) which will require spending 8 SC (same thing I just said, but down from scratch instead of taking previous work and working backward.

TLDR: 8 SC (9 at worst, 7 at best if you level up at some point) is pretty darn good for a min-cost Black Princess. Just saying
