How are crit and bleed (and stun) chances calculated

[Gyozo]

1. I don’t understand how bleed and crit and stun chances are calculated. When do I add directly to crit chance? (10% + 10% = 20% crit chance) and when do I multiply (10% * 10% = 11% crit chance).
2. Is the character sheet accurate? I don’t understand the values I’m seeing there for crit bleed stun and other effects.
3. When a specific skill adds bleed/stun/crit chance can I see those chances somewhere in the character sheet?

Thanks.

1. Add all the flat sources of crit to the base (usually 5%) then multiply by the sum of all % increased crit chance.

2. Yes & no. It will double count everything it can (so % increased damage will be added in to every line but only gets used once in the calculation) & it doesn’t include and skill specific modifiers.

3. No.
