Ok nerds, I need some math here.

% chance to get x1 -0.05 on Sin bracers:

9.16%

What would be the % chance for X3? #'s speaking.  :police:

How to count chances?


Taking r8 wrists as an example:
Chance of getting -int on wrists is the same for all classes, roughly 8.16% (0,0816*100%) per stat.
For 3 parts it's simple, just multiply all the values 3x.

chance * chance * chance * 100%

3x -interval is 0,0816*0,0816* 0,0816 * 100% = 0.0768%


For 2x and 1x you're better off using the calculator and putting the formula there:

3!/(2!*(3-2)!) * chance * chance * (1-chance) * 100%
3!/(1!*(3-1)!) * chance * (1-chance) * (1-chance) * 100%

2x -interval is 3!/(2!*(3-2)!)*0.0916*0,0916*0.9084*100% = 2.28%
1x -interval is 3!/(1!*(3-1)!)*0.0916*0.9084*0.9084*100% = 22.6%


To sum up:
3x -interval is 1 in 1300 tries in average   (100%/0.0768%)
2x -interval is 1 in 44 tries in average
1x -interval is 1 in 5 tries in average




For archer / sin chest:
Chances for getting -int on wrists are same for sin and archer, roughly 1.47% per stat, which gives:

3x -interval is 0,0147*0,0147* 0,0147 * 100% = 0,00032%
2x -interval is 3!/(2!*(3-2)!)*0,0147*0,0147*0.9853 * 100% = 0,064%
1x -interval is 3!/(1!*(3-1)!)*0,0147*0.9853*0.9853 * 100% = 4,28%

To sum up:
3x -interval is 1 in 315 000 tries in average
2x -interval is 1 in 1565 tries in average
1x -interval is 1 in 23 tries in average




For archer boots:

3x -interval is 0,0015*0,0015*0,015 * 100% = 3.375E-6%
2x -interval is 3!/(2!*(3-2)!)*0,0015*0,0015*0,9985 * 100% = 0.00067%
1x -interval is 3!/(1!*(3-1)!)*0,0015*0,9985* 0,9985 * 100% = 0,45%

To sum up:
3x -interval is 1 in 30 000 000 tries in average
2x -interval is 1 in 148 000 tries in average
1x -interval is 1 in 223 tries in average
