It was 25 on the 1K map and 24 on the map I was aiming for another ranked, I'm not too sure because I'm not very good at matching offsets either.
Also, I think there may still be some placement discrepancies, so I'd like to ask another person to do a mod or something to confirm if possible.
i think i agree with gt. check quick/sharp sounds such as snares since this is an electronically produced song to produce fully accurate timing
