Dual Blader's HP: Job Advancement

I posted on EF and SW forums already but didn't get a reply (or did get a reply, but the guys didn't know the answer), and figured I may as well post here too;
Does anyone know at which job advancements do Dual Bladers gain a HP and MP increase? I know for sure the level 20 advancement does, but I'm not sure about the others.
An answer would be lovely!

Id say yes, mainly because (iirc) all jobs get a boost when advancing.

All these questions about Dual Blader HP are simply annoying.

 Before 3rd advancement

 After

 Before 2nd+ advancement

 A bit after, sorry missed actual advancement

You get HP increments every job advancement.

Yeah, I didn't want to seem too annoying because I know a lot of people are wondering, but I hadn't seen anyone ask this question and couldn't find an answer myself before. That's perfect though, thanks Danny.
