第四則是 Mark_GGG 留的 (應該是官方人員)

Note: Even with no evasion rating (such as because of Iron Reflexes), you
still have a 5% chance to evade, and that will double to 10%.


另外，再配上 wiki http://en.pathofexilewiki.com/wiki/Arrow_Dodging

Note that this doubles evasion CHANCE, not evasion RATING. This means that if
your evasion chance were 45%, it would be doubled to 90% vs projectiles.

If you were to take the Iron Reflexes Keystone along with this one, your
overall Evasion rating would be lowered to 5% (it can never be below 5%), and
this passive would increase your chance to Evade to 10%.



應該就如同 softseaweed 所講的一樣 機率值x2。(但還有上限頂著)
