Can someone please explain how defense works?

Use the calculator in the post above, to work out what your modded armor/resistance is by matching the percentage reduction from your stats screen and reading out the flat number the calculator gives you. Now double the flat number (if it was 400, use 800) and enter it back into the calculator and it will give you the resultant damage reduction that sith trooper will have in combat. Use 2.5x if you want to simulate for Defense Up,

Does the defense ever cap at some point? Like if he has 30% base armor, doubles it to 60% defense and then gives himself Defense up wouldn't that give him effectively 90% armor? Or does defense up only go off of base armor which would be 75% total damage reduction.
