? sorry, reopen, and It would be good to refer to http://www.chien.jp/Chien8/opmovie.html
Compared to other sections, the kiai of normal and hard seems to have a rather less dense rhythm, making it less difficult.
In both normal and hard, 1/1 beats are used more often in kiai than in other sections.
In normal, 01:11:348 (1,2,3,4,5) - etc, it's too easy than other section.
In hard, uses the pattern like 00:30:927 (1,2,3,4) - in the other section, but kiai has an empty space like 01:11:980 (2,3,4,5) -, so it feels easier than 00:30:927 (1,2,3,4) - like this.
Also, even if there is a difference in SV for each section, the density difference due to 1/4 rhythm will have more influence.
Overall, it seems necessary to adjust both the kiai and the rest of the section.
For example, Hard is to change a few 1/4 reverse sliders to triple in kiai, reduce the frequency of 1/1 sliders. and overall the map is already dense, so if you reduce the frequency of triple or 1/4 reverse slider in other sections, I think it would be good.
In the case of normal, it is better to buff the kiai, and to nerf the other sections, especially 00:50:822 (4,1,2,3,4,5) - It would be good to fix these high-rhythm-density patterns by nerfing them.
From insane to the Extreme, 00:48:612 to 00:53:664 - and 01:13:875 to 01:18:927 - have the same rhythm/pattern, but the difference is clear in music. 00:48:612 - vocal rhythm is 3/4, 01:13:875 - is 1/1, but more instruments are added to the background. I think this deserves to be a problem. the two sections of music are different, it would be good to express different patterns and rhythms. for example, 00:48:612 - ~ 00:53:664 - it would be better to fix both the pattern and rhythm according to the vocal.
