It is hard to do any exact investigation, because you can't see Stamina as a number in-game. One approach used by @devsifmatch in early investigations was to take screenshots before and after a note and use a script to calculate lost stamina by examining the area of the gauge that is still coloured. The smaller the max stamina of the formation, the more accurate this could be. An alternative could be installing a cheat engine like GameGuardian to attempt to find and watch the exact memory location of the remaining stamina. — Suyooo 2020/10/14 13:26 UTC

I guess damage gimmick notes might work too, since they appear in the skill log. But do they follow the exact same formula? — Suyooo 2020/10/20 20:34 UTC

Here's a neat sheet that should help finding the correct note damage formula:

How to use - make a copy, fill in data (copy necklace strengths from the bottom, not from the game). The bordered calculation area below lets you define what should be tried - either FLOOR to round down, or the name of a column header in the Q to W range to multiply by that factor. You can also add new factors there if you think they are needed. Move parts of the calculation around until it hopefully matches all your data. — Suyooo 2020/10/20 20:36 UTC

Idea for the “stamina remaining affects accs” problem in the sheet: make several lines - one for the damage gimmick (where the skill log will tell you what the damage is), and then one for every note before that gimmick note (where you can't enter real damage). Make the “stamina remaining” field of each line calculate itself from the previous calculated damage. This way, a correct calculation for the damage gimmick line should imply all of the note damages are correct as well. — Suyooo 2020/10/22 16:31 UTC
