possibilities of the Chaos Scroll

Hi All,

we all know how Chaos Scrolls work. It adds -5,.......,+5 stats if the scroll worked.

But im a bit confused of the possibilities regarding the stats the Scroll add or remove.
Tried to search the forum and the net but couldnt find any answers to my question.

I tested now around 10 or more Scrolls. most times i got +0 att when the scroll was successful.

the Chance of having +0 ATT is 0.6 x (1/11) <-- 11 chances (-5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5)

Is it really 1/11 for all stats or does the chance decrease the higher or lower the stat is which the scroll adds or remove.
for example. Total chances 60. Chance for 0 Att is 30/60 * 0,6 Chance for +1 att is 10/60* 0,6....... for +5 is 1/60*0,6

So my question is, does such a possibiltytable exist (not this one but in a similar way) or do i have terrible luck with landing all time +0 ATT when the scroll worked?

thanks for your help

Bit too tired to dig deeper into these threads, but these two should help:
