00:44:256 - this second half of the kiai section is more intense, but it is mapped somewhat easier (three 1/4 triplets) compared to earlier (two 1/4 5-plets in 00:38:062)
you could make the second half of the kiai more intense, e.g. make 00:44:256 and 00:50:449 1/2 7-plets instead
01:36:128 - Circle unsnapped by 2 ms. 01:36:709 - Circle unsnapped by 2 ms. 01:37:096 - Circle unsnapped by 2 ms. 01:37:483 - Circle unsnapped by 2 ms. 01:38:838 - Circle unsnapped by 2 ms.
02:04:965 - i'm not sure why this is the only part that has 1/2 notes in this section, you can maybe try removing the 1/2 notes here and add 1/2 notes in the later section 02:10:191 - 02:22:578 for the rising song intensity
if you applied the change in the oni in regards to the slider apply this in muzukashii as well starting the slider at 02:22:578 and ending it at 02:24:126
