Diablo® III

I'm trying to ignore some work today and looking over my profile, planning what upgrades I want to hunt for this weekend and I noticed something.

Here on the forums, it shows my +Crit Hit Chance as 49%, but on Diabloprogress and D3Up it's listed as 54%. Can anyone tell me where the other 5% is coming from, as I can't seem to figure it out and I want to make sure I take it into consideration when looking for my next upgrade.

It shows the ammout your gear increases you critical chance by which would be 49%, all characters naturally have a 5% chance which totals to 54%

Ahhh, perfect. Thanks! So no need to take anything else into account.
