Well, here's an additional thought for you.....
The info given on the wikis is not a bunch of random unsupported "maybes". The people who posted the armor cap info, did so after doing extensive testing. So, the info on there is most likely correct (and both wikis agree with each other, btw).
If you really want to confirm it for yourself, I can think of a way for you to do it. You can equip yourself with a few armor boosting skills and go to some low level area and let some enemies attack you. Do this first without using any skills and note how much damage the foes do. Then use some configuration of equipment and/or skills to give yourself exactly +25 armor and again note how much damage the mobs do. (Btw, this will require, for consistancy, that you repeatedly rezone to engage the same mobs over and over). Then you can repeat the process using combinations of skills that would give more than +25 armor and see if the damage from the mobs goes down below the +25 level you previously set.
You can see that, due to variances in the damage done with each individual attack, that you would have to do many, many repetitions of the tests to get reliable results.
(You could also do the tests using 1v1 PvP type settings too.)
Have fun!
