oh yeah..does the songs have their own effects? I found "My Best Friend" to give much more score than "Shiny Smile"...now I'm thinking if I'll use that song for my 5th release on my next playthrough though it's kinda slow..
Err, no. BPM's are pretty much the key to score high. If you think you scored better it's because you got more danketsu or because you're playing a stage with modified multiplier settings.
You should listen to Cael.
According to the Japanese wiki, faster songs (with more beats) tend to give less stats than slower ones. Whether or not this is related to score scaling, I don't know. Voltage gain decreases as BPM increases, and I think it's that way for score too... I just think that if the wiki is true, you don't get good stat bumps either.
That being said, previously in the thread, we talked about Burst scores not scaling. Since Bursting really helps out your score late-game, faster songs will give you more points generally even with scaling in place.
Pretty much, songs with 180 bpm give approx 50% more points when compared to 120 ones to offset the difference in beats, with the same stats I get 375 per beat or 250 with the same modifiers for 120 and 180 respectively, and gained voltage is also scaled in the same way.
Then again, like I mentioned before I never bothered comparing, or observing, gained scores etc with songs with beats in between those 2 values cause I'm lazy so 170 and 130 bpm songs might produce unexpected results.
Also, like mentioned way before NBGI made a boo-boo with the way combo bonuses are calculated and with the bursting thing.
Of course, it doesn't affect anything, I don't think. Unless the number of times you appeal and stuff give you bonus lucky stars? I doubt it.
They don't, stages are only for showing off your scores imo.
For accidents during a fes battle, play Haruka's story. You'll get accidents all the time though it'll only annoy you and not break your scoring and combo iirc but that doesn't matter neways.
