Your wording in the calculation is incorrect in regards to snare. This is clearer:
(Speed Difference x 10%) + 25% (if there is dodge) + 25% (if there is flying but it won't work on other flying troops unless they are snared) + 15% (if there is blind) = Evade Chance
Great article!
Ah, yes some people may be confused about that. I will edit it right now!
