Rest moments: Following sections do not have sufficient rest moments. Muzukashii is also quite close to Oni, overall, when it comes to density - this will help with that issue as well!
01:31:581 - to 02:08:833 - If you want to do it similar to the previous sections, delete:
01:32:674 (7,8) -
01:39:131 (7,8) -
01:45:389 (7,8) -
01:51:846 (7,8) -
01:58:005 (23,24,25) -
alternatively, 01:37:541 (15,16) - 01:43:700 (15,16,17,18) - etc. would be good fits.
02:55:422 - to 03:29:992 - Can do something similar to Oni (if you have seen that mod first!)
02:59:197 (17,20,22) - deleting these creates 3 1/1 rest moments, which can act as substitute.
03:06:349 (55,56,57,58) - 03:12:707 (91,92,93,94) - 03:19:064 (124,125) - 03:25:422 (156,157) - are spots suggested in Oni
same procedure as in the section above: Rest moment every 4 bars.
03:38:137 (33,34) - 03:44:494 (67,68) - 03:44:494 (67,68) - 03:57:210 (135,136) -
there are some 5/4 rest moments left, but having asked some people I think it's fine at this song's BPM and structure.
Two critical spots remain:
01:45:488 (7) - needs to be deleted (there's ~16/1 before and after until the next rest moment, guideline requires a rest moment after 16-20/1 of continuous mapping)
One of these: 03:57:409 (129,131) - needs to be deleted.
