Based on the following Unholy DK's Youtube channel (https://www.youtube.com/watch?v=TIBJFJYuSng), I've tried my best to analyze the proc chance of legendary wrist, Instructor's Fourth Lesson. The player is a Korean Unholy DK under the name ***킨 in 줄진 server. I will call him "Player" below.

- I've counted how many wounds were stacked per FS (and also by Infected Claws), and how many were popped per SS
- Did only for Nythendra, Renferal, Dragons of Nightmare, Ursoc. I will upload the rest later, including Trail of Valor.
- Below analysis is not completely accurate due to the limit of wound numbers. For example, let us say Ursoc has 6 wounds and player strikes a FS making it total 8 wounds, I'm considering that as 2 wounds stacked. Same goes with SS, if Ursoc has 1 wound and Player strikes a SS popping 1 wound in total, I'm considering that as 1 wound popped.


<Nyethandra>

Wound Stacked
1 wound: 1
2 wound: 16
3 wound: 17
4 wound: 16
5 wound: 2
6 wound: 3
Total: 55 FS
Average: 3.2 wounds stacked per FS
Comment: Player has Shadow Infusion and not Infected Claws, and yet there is 1 wound stacked. Not entirely sure what happened here but I'm including it in the stats anyay.

Wound Popped
1 wound: 57
2 wound: 29
3 wound: 3
Total: 89 SS
Average: 1.39 wounds popped per SS
Comment: This is before Player acquired his bracer.

<Renferal>

Wound Stacked
1 wound: 2
2 wound: 15
3 wound: 13
4 wound: 20
5 wound: 5
6 wound: 4
Total: 59 FS
Average: 3.39 wounds stacked per FS
Comment: Player has Shadow Infusion and not Infected Claws, and yet there is 2 case of 1 wound stacked. Not entirely sure what happened here but I'm including it in the stats anyay.

Wound Popped
1 wound: 1
2 wound: 15
3 wound: 17
4 wound: 7
5 wound: 6
6 wound: 1
7 wound: 1
Total: 48 SS
Average: 3.19 wounds popped per SS
Comment: This is after Player acquired his bracer. The result is quite staggering.

<Dragons of Nightmare>

Wound Stacked
1 wound: 43
2 wound: 15
3 wound: 15
4 wound: 18
5 wound: 6
6 wound: 12
8 wound: 1
Total: 67 FS + 43 Infected Claw
Average: Excluding 1 wound (Infected Claws), 3.84 woundsstacked per FS
Comment: Interestingly, the 6 wound is twice as much as 5 wound. Nice RNG. There's a scene where he stacked 8 at once, and I'm probably very wrong with this but no matter how many times I view it, it's 8 stacks with one FS (Don't burn me alive for being wrong)

Wound Popped
1 wound: 10
2 wound: 24
3 wound: 25
4 wound: 11
5 wound: 3
6 wound: 2
Total: 75 SS
Average: 2.72 wounds popped per SS
Comment: 10 of 1 wound popped. Bad RNG.

<Ursoc>

Wound Stacked
1 wound: 42
2 wound: 12
3 wound: 18
4 wound: 22
5 wound: 4
6 wound: 3
7 wound: 1
Total: 60 FS + 42 Infected Claw
Average: Excluding 1 wound (Infected Claws), 3.52 wounds stacked per FS
Comment: There's a 7 stacked scene. Maybe I'm wrong again, or maybe it was stacked instantly with an Infected Claw proc.

Wound Popped
1 wound: 4
2 wound: 17
3 wound: 15
4 wound: 12
5 wound: 7
6 wound: 3
7 wound: 2
Total: 66 SS
Average: 3.3 wounds popped per SS
Comment: Much better RNG than the Dragon fight.


<Conclusion>

- Out of 3 fights with the legendary bracer, Player used SS a total of 183 times and
1 wound was popped 15 times (8.2%)
2 wound was popped 56 times (29.0%)
3 wound was popped 57 times (31.1%)
4 wound was popped 30 times (16.4%)
5 wound was popped 16 times (8.7%)
6 wound was popped 6 times (3.3%)
7 wound was popped 3 times (1.5%)

- Considering 7 wound pop is only 1.5%, the bracer nerf in 7.1.5 (1~5 >> 1~4) is not a significant change at all. It's even almost nothing. However, if Blizzard adjusted the proc chance itself, then we would need to do the analysis again to see the impact.

- Again, the above stat is not entirely accurate due to the limit of wound number able to be stacked and popped. So just use it as a reference.
