In the Player Guide linked from the R60 email, the explanation of matching armor bonus is confusing

In the section titled "Combat Tips" there are a few sentences explaining how a bonus is calculated for your armor based on whether the pieces match the chest piece.

It says that if all pieces are light, you get 12.5% bonus.
It says that if you are wearing two plate pieces one on the chest and one being the helm and all the rest light, you get 2.5%.

Now, I only count five armor slots for this purpose. Do you count more than five armor slots for this purpose? If there are five armor slots, by the first example the total bonus would be 10% not 12.5%. Because in the second example you aren't giving the bonus for the chest piece. In the first example you give 12.5% but if you don't count the chest, it should be only 10%.

I only count chest, legs, boots, gloves, helm. Are there any other slots that can have heavy or light armor on them?

If you add "cloak" I call foul. Thats not fair to the heavy armor users. Unless you introduce a plate armored cloak. Or, I guess it would be fair to give the 2.5% cloak bonus to a heavy armor user regardless of what color or material their cloak is.
