Extracted from TeamPA's Attack Page:
The probability:C= 0 which hits against the vital part: 6.6% 1: 12.5% 2: 25% 3: 33% 4: 50% (C: critical frequency)
A) lucky + ラッ keypunch C= 2 all skill
B) duck ネギ + green onion C= 2 all skill
When A) B) is, or less is invalid
C) " it comes, between め " C=C+ 1
D) from て chop / being concerned / club hammer / drill fence / at the time of aero blast / cross チョモ iISB プ, C=C+ 2
The E) it has, in the thing " the focus lens " C=C+ 1
Alright here's what I've understood so far...
There are 5 possible values for C which is the rate of Critical Hits (Hitting the Vital Area) and they are:
0 - 6.6%
1 - 12.5%
2 - 25%
3 - 33%
4 - 50%
Now it seems if Chansey (Lucky) or Farfetch'd (Duck) are equipped with a certain item then C=2 else C=0 (A & B)
Next it checks if some condition is met... I'm not sure what it is yet... I'll post it as soon as I find out... but if the condition is met C=C+1 (C)
Next it checks if the attack has a high CH rate... if so C=C+2 (D)
Finally if Focus Energy was used C=C+1 (E)
As soon as I figure out what the requirement for C is I'll post it...
BTW - It notes earlier:
