Indeed 1/1 dashes at 187 bpm feel too weak that are around 1.6x e.g. 00:24:428 (2,1) - Increasing to 1.8/1.9x would do well here.
Dashes such as 00:00:497 (2,3) - which are 1/1 at 152 bpm, feel even worse. As 1.6x here is more like strong walks or even a weak tap dash. I would suggest reducing them to 1.3x if you want to keep a walk. Otherwise, increase to be a similar distance as 00:02:668 (5,1) - or maybe 2.3x as that is already more than enough to make a clear dash.
