Just steal take timing from other maps, you can assume ranked version are timed
95bpm, 2321offset and reset at 32321offset (I think)
I got 194bpm, 50offset
I don't think chorus is faster, but the beat is reset at multiple places and I'm not good at it. What I mean is that 00:59:276 - chorus play on the red tick instead of white for instance (and a few other places outside of chorus) and there are some 1/3 or 1/6 hidden in there. I'm leaving you with that, good luck :3
I am working on the map and I think I have great problems with timings. I did my best to find the correct BPMs and offsets, but despite this I cant play my map because the is still no rythm. Check them, please.
