lothario - what do you mean "you dont want to spoil too much?!"
spoil ahead if you know the numbers. where did u get your info from, mate?
if critical attacks to 130% damage than no thanks. i'll save my perk for something else. if they do 200% or more than i'll go for them.
and how much is bleeding and armor penetrations?! this info seems imperative! i cant believe it's still unknown.
It's not unknown, a bunch of us in the Spoilers forum have done extensive in-game testing of all these (and many many other things). See the thread(s) below:

That link is just the latest thread out of a series of eight so far. If y'all read through them, you might be surprised at what you learn about Skyrim.

Edit: As an aside, I have personally found errors in the UESP wiki concerning Skyrim, and don't even get me started about the loading tips in-game. Some of those "tips" are flat-out wrong. One example: a 2H sword does not swing faster than a 2H axe -- they swing the same speed. Test it for yourself, and you'll see. All the things we've posted in those threads are reproducible by you, as we lay out the testing procedures and post the results that you can duplicate on your own if you wish. If you want to become a contributor in our series, come on over and help out however you like... plus, we are more than happy to answer any questions you have.
