Are we hitting a cap on percent based buffs?

This morning, I did some testing on Armor passives and Shadow Veil. All results are based on recording 60 hits taken, discarding critical hits.

For reference, my Rogue has 1439 Armor, so the 5/5 Armor passive should add another 71.95 Armor. Total armor with the passive should be 1511.

Below are my results:



Now, without knowing how armor affects damage reduction, it is difficult to assess how effective 5/5 Armor passive actually is.

While looking at the raw averages, one would assume that 5/5 Armor + Veil seems to stack; however, if you look at the Standard Deviation value, Veil with and without the 5/5 Armor passive implies that it does not stack.

Based on this, I can only conclude that the 5/5 Armor passive has very little value, and that the armor passive does not stack with Shadow Veil.
