offset should be +15 -> so you need a rebubble (also for the first redline, its messed up because when you look at the timing right before the second redline its 1ms off pls make it line up)
quick thoughts tho
compare 01:23:431 (1,2,1) - and 03:21:275 (1,2,1,2) - I'm not really a fan of how you ignore the vocals the second time and not the first, it comes off as inconsistent, if you were going to map 03:21:814 (1,2) - i would say ignore the vocals in the first part as well. I would say you have to pick between the two
some streams are very clearly additive like 04:25:317 (9,10,11,1) - 04:11:215 (1,2,3,4,5,6,7,8) - 04:11:215 (1,2,3,4,5,6,7,8) - etc pls look into this (most noteably the yellow tick notes for them)
04:29:898 (1,2,3,4,5,6,7,8,9) - this is extremely ambiguous but I think its still 1/3 (or 1/6 for this bpm)
04:36:365 (1,2,3,4,5,6,7,8) - most of these are additive
also 04:21:455 (1,2,3) - stuff like this is technically additive but its good because of the guitar stuff so pls keep
good luck
