it's calculated at the Exp gained divided by total of all the resources needed to build decoration. I didn't like how .01 looked, so I expressed it as a % which shifted the decimal by an magnitude of 2.

I used the % notation more as a shorthand for the decimal shift than an actual %. If you love math, than you are correct that I bastardized it. :D Feel free to adjust it to suit your tastes. I'm not particularly attached to that notation form.
