Thanks, for your help.
Even more questions.
1. I noticed that doing Hell's training increases your idol's appeal by about 1-2 points for each session. Since I've started in January and working my way down the year, can I redo these Hell's training next year thus getting permanent appeal increases without a limit?
2. I noticed certain levels like 35, I think there seems to be a jump in your idol's appeal points (not just the usual single 1 point) (My idol went from like 137 to like 162 after a level up after Hell's training, and I can't explain otherwise why it happened. Are there other certain levels where there's a jump in appeal?
3. And, for any answered question from my previous post, if you all know the answer.
Thanks.
1. How scoring is calculated in Stella Stage is different from Platinum Stars - before your score per note was decided by (effectively) appeal score/ idols present *difficulty level modifier, meaning that the more notes a song has, the higher score you'd get.
In Stella Stage, they standardize by calculating how much you can theoritically score (with a formula similar to PS, but with some sort of multiplier that's hidden and constant), then divide that score by the number of notes in the song, regardless of difficulty. Any skills gained from CP that affect appeal are added after this calculation is done.
The final number is rounded up, incidentally, which effectively means you can score very slightly more in Master compared to pro, but it's only ~1-2k difference, assuming full comboing both.
Since the Hell Training song has the most notes in the game, the rounding up becomes VERY apparent, and if you kit out your 5 with the unit quintet skills (They count) your score jumps up significantly.
Also, the costume is set for Hell Training (red headband and training tracksuit/swimsuit) and the appeal level of those items will count for that song.
tl;dr - Same 5 units + 5x quintet +5 appeals +leader with all the quintet skills + level 7 training uniform/swimsuit + level 7 red headband = easier time to full clear due to higher appeal score.
2. There are breakpoints where you will receive more points than normal.
Not sure for level, but I think they're level 35 and 65 respectively. For Burst and Omoide, they're level 10 and level 15. They give substantial jumps to their respective score, but in Burst/Omoide's cases, they also then require a very high amount of exp to get to 11/16 (As in 150+ uses).
Generally, you should be able to FC any stage (with a little lesson boosting) once you're level 70 15/15 for leader with a properly kitted out leadership tree and 50 10/10 for the supports with a full support tree for the type you're doing.
The previous question - the changing idols/poses are just fluff.
