Hello! Just wanted to ask about UR. im not talking about average UR, but UR between "clicks" lets say.

Clicks	BPM
0 0
1 0
2 0
3 51.72
4 50
5 49.18
6 48.96
7 48.21
8 48.25
9 48.23
10 48.25
11 48.2
12 48.33
13 48.08
14 48.03
15 47.91

I'm not the greatest with maths but would I be correct in understanding that the UR between lets say clicks 8 and 9 is 0.2? cause (48.25 - 48.23)x10
if not, then perhaps some assistance will be helpful.

I read the wiki and understand that the average UR is the standard deviation of hit errors multiplied by 10 so yeah....

why do you have bpm. The maths of the unstable rate (im pretty sure) is this. You have the perfect timing 0ms, say you have 5 notes,
1: -5ms
2: -2ms
3: -7ms
4: 0ms
5: +4ms

You then work out the standard deviation:
Find the mean: -2
Find the square differences:
-5-(-2)=-3 etc:
(-3)^2 =9
0^2=0
-5^2=25
+2^2=4
+6^2=36
Find mean of square differences: 14.8
square root 14.8=3.85
So the standard deviation is 3.85
Then if ur is sdx10
UR=3.85x10 =38.5
