There's a consistency problem in the kiais that I believe it should be fixed, it doesn't really make sense to map 01:10:548 (2,3,4,5,6,7,8,9,10,11,12,13,14) - like a 1/6 long pattern but then map 01:12:912 like a 1/3 pattern, the sound is almost the same if not the same, it makes a really big gap in difficulty that shouldn't exist on a similar sound.
Things like 01:17:093 (44,45,46,47,48,49,50,51,52) - make sense to map them differently as the sound is 100% different, but there should be consistency on things that sound similar otherwise the map's difficulty will be all over the place.
Either buff it to match or nerf the 1st one to match, same applies to the other kiais like the last one at 03:29:639 - 03:44:912
