3rd job advancing at 80?

So I trained on my outlaw yesterday for the ring, and since it was 2x, I didn't have time to do my job advancement. Will I lose on some hp by doing it now at 80? If so, can anyone do the math?

You don't get HP for 3rd job.

You don't get HP for 3rd job.

But, is the hp gain per level higher in 3rd job? That's the question.

No.
