Well, it gets even shakier if you read the description...stuff like "i think these are how the tooltips work but I don't even have all classes @50"...and "the only class I play seriously is MNK"...guy doesn't come off as having a lot of experience or confidence in his findings. And there's no indication of time here so as far as nin goes, it could be before the slight nerf. And his drg max #s are low so it probably is before that update. Wouldn't account for all the discrepancy between nin and the other jobs, but he may also have some misunderstandings of how things work to put it that high.

The practical answer is that no, it's not accurate. It has the potential to be, but he may not be the one to put that together, at least not without a few people who know other jobs' rotations and abilities better.
