Guild Wars 2

Recently I bought new pistols, Ruinmakers of Accuracy. Both should provide me 10% crit chance + bonus from 180 precision. However my crit rate is increased by barely 9%. I’ve been looking for some crit chance formulas and I found one which is pretty accurate. After doing some calculations it came out that only precision bonus is applied, sigils aren’t working. Here are proper screeenshots and calculations according to formula below:
[(Precision-916)/21]+4
Subtract 916 from your Precision to find the amount you have above the base. Divide that by 21 to find the extra critical chance you’ve gained from that extra Precision. Add the 4 base crit-chance, and you have the final critical-chance percentage.

No weapons equipped – 40% chance at 1682 accuracy
[(1682-916)/21]+4 = 40,47… – goes rounded to 40

1 weapon quipped – 45% chance at 1772 accuracy
[(1772-916)/21]+4 = 44,76… – goes rounded to 45

2 weapons equipped – 49% chance at 1862 accuracy
[(1862-916)/21]+4 = 49,04… – goes rounded to 49

Sigils do not stack, sadly its not written anywhere but they dont…

But not a single sigil is working, that’s the matter. If it was like you said, I’d have 54% crit chance

I can confirm that issue, Superrior Sigil of Accuracy adds no crit chance at all.
