I'm not entirely sure about that, but at least for now I'll take your word for it.

The question still remains as to whether or not he is accounting for all of his loads or not.

As good as the tool is, it isn't taking into account all of the factors that would affect FE, but having it account for all factors would be impractical for the vast majority of people.
