Evasion and Critical chance granulation?

I heard minimum granulation for evasion and critical chances is 5%.
Is this true, and if so what other abilities have similar behavior?

Does anyone have a testmap for this?

I know that the fact with 5% is true for bash, critcal, drunken brawler and most of the on hit passives, however if i recall the information correct evasion is working proper with 1%.
There wes a thread some time ago, if i find the thread i gonna edit this post.
---Edit---
Found it >>>thread<<<

All the more reason to find a Damage Detection System and trigger Critical Strike.

Honestly though, I don't see why you would need anything other than chances that are multiples of five. Although, just the same, I don't know why Blizzard doesn't just enable them at numbers other than multiples of fives...
