00:22:250 (1,2) - you could maybe give this a spacing increase like you did 00:19:284 (1,2) - ? would help make your "spacing increase for strong sounds" thing you have in this section consistent
00:18:973 (3,1) and 00:37:859 (4,1)'s spacings were meant to highlight the kiai start/end time
the difference in sounds in 00:21:781 (3,1,2) are much less noticeable than those since these are fully inside the kiai
