Just a quick note. In ED3 (and earlier), an Excellent -- not Extraordinary -- success is an Armor-Defeating Hit. I'm assuming that's what you meant, but just in case you've been playing things with Extraordinary successes...

For sure, there are situations and items in ED3 (and earlier) that modify the result level needed, but out of the gate, Excellent = Armor-Defeating.
Take kaer, James
