I just testplayed your diff again and I was hitting a lot of 50s and sliderbreaks on 1/16 sliders, so I tried to understand why this happens.
And I understood.
Basically, at this BPM a 1/16 beat is 22 ms. You can check it on your own.
And according to
this table at OD9 you will get a 100 if you exceed 24 ms window.
So, basically, it's harder to hit a 1/16 slider without a sliderbreak than to hit a 300 circle.
If you start hitting the 1/16 slider 22 ms later than intended, then you're going to miss the first circle and the first repeat as well, which results in a sliderbreak.
You will get a sliderbreak if you hit the slider start with an accuracy for just a 100-ish hit. Does it deserve to break the combo?
That's really not any good. This means that anyone who can't hit a good 98% accuracy will be forced to break the combo at those 1/16 sliders pretty often.
But if you use a 1/8 slider, the hit window is doubled, making it 44 ms which is a lot better (almost like a 100 window for OD5-6).
I think you
must change 1/16 sliders to 1/8, otherwise it's quite unplayable for most non-pro players.
