Quickie: Some Thinking On Evasion

I'm currently working on coming up with meaningful stats for our test force. As part of that, I did some thinking on our Evasion mechanic. As in, what should each level of Evasion represent?

Here's what I've got:

I'm going to remove 'Long Range' as a modifier for evasion, as I don't think that possible to-hit penalties should go over 2 points on this scale, and our battle space is too small for range to be a big deal anyhow. :)

Thoughts?

Edit: This is what I mean by 'Swarms'. :)
