How much hit chance i need for not beeing evaded?

[Topogigio_BR]

I was trying to retake a fort other day with my mark i was shooting tower guard and had 9 evaded in 14 shots, 64,28% evasion, and i had 611 hit chance, so i am asking how much do i need for not being evaded.

I still think this hit chance/evasion is kind of messed, seems no1 really knows what really means if you have 1k hit chance or 500 hit chance, for me it should be simple 611HC/(69evasionx10) should be 88,5% of hitting a target.
