Lead me through Grace...

Good Day,
I have been running this skill and it is not calculating correctly. It states 1 spirit for every 6 energy shield and 1 spirit for every 15 evasion both on equipped body armor. I did the calculation and it is off by at least 100 spirit. This make so sense if it states this in the skill. I am not counting any spirit on the armor since that says it will not. I do not know if this was intentional or a issue with the game. So my question is when is this going to be fixed?
