Damn those set SAs lol
Your ratio found compared to based on your mf looks pretty solid on unique/set/rare/magic, you’ve just been screwed on IDing uniques.
Definitely screwed on ID'ing... sorta.
However, I am not sure if I am reading your message correctly, but just to clarify...
The ratio I have listed is based on MF calculators predicting chances of finding those rarity types based on my MF. So, for every 30 magic sacred armors I find, I should also find approximately 5 rare sacred armors, 3 set sacred armors, and 1 unique sacred armor.
I have found a total of 12 unique sacred armors in this entire grail.
Since the last unique sacred armor I found, #12 (2 years ago now), I have found 36 set, 48 rare, and 181 magic sacred armors. So, using the theoretical ratio above, at worst I should have found 6 unique sacreds (181 magic sacreds found / 30 magic sacreds per unique theoretically = 6.0 unique sacreds theoretically) and at best 12 unique sacreds (36 set sacreds found / 3 set sacreds per unique theoretically = 12 unique sacreds theoretically), but I have found 0 since then. And this makes me real sad.
