I do not know the reason yet, this is a report for a situation that happened to me and atleast @lament pike too.
We login on website to get our appraisal. Enter character to be apraised, and get a rank lower than expected. We do not confirm.
I tried again once more and get same result i did not expect (i got S+ ranking while i calculated with the data shared that i have minimum over 50k, SS being 45k-99k).
I connect to the game. I do nothing but go to website, and appraise again -> SS rank given.
@lament pike shared same situation (i do not have his calculation), but he connected to website and get SS rank, do not confirm and leave.
After connecting in game he appraise again and get appraised at SSS rank.
To my understanding, one of the stuff that is supposed to take in count is not before we connect, then it refreshs and take it in count. Could be dice / wyrm saved up for example.
In my case, here are my screenshots from earlier today :
1st appraisal. Calculation. 2nd appraisal after connect.
