yes a particular node at 85% is per hit, but when you're getting 3000 / 5000 tries, you have to be close to approaching the relative point


the logarithm needs some work, a checksum where the % was taken into account that based the upcoming hits off the previous hit would be more accurate unless the point of it is to piss people off and make yields lower than actual, in my experience I have never out of all the mining/gathering i've done, ever come remotely close to the %'s described
