Where did you get it from?
Of course, I assume that you already have 100M Cr to get there.
C1 = 10k Merits, 95M Cr spent;
C2 = 1/2 x C1 = 5k merits, you need to get 5k merits to maintain 10k merits; 41M Cr spent, 1000 Cr earned;
C3 = 1/2 x C2 + 1/4 x C1 = 5k + 2.5 k, 2.5k merits are required, 20M Cr spent, 50M Cr earned;
C4 = 1/2 x C3 + 1/4 x C2 + 1/8 x C1 = 8.75k merits, 1.25k additional merits are required, 10M Cr spent, 50M Cr earned;
C5 = 1/2 x C4 + 1/4 x C3 + 1/8 x C2 + 0 x C1 = 8.75k merits, 1.25k additional merits are required, 10M Cr spent, 50M Cr earned.
Where I am wrong?
at your 5th week, you're getting
1250 which is 1/8 of 10k from c1
1250 which is 1/4 of 5k from c2
2500 which is 1/2 of 5k from c3
and 1250 from your last cycle c4
so you will need 3750 to get 10k, and since the 10k you payed from c1 is why your past cycle's have been so cheap and its not going to factor into your future cycles, you're going to have to average 5.33-5.34k per cycle to maintain 10k, which would cost 50million, maybe 40 million per cycle if you spend a lot of time, and at that point you're pretty much just wasting a lot of time and haven't really made much, grinding.
