Can dual blades save points between jobs?

Let me just make this clear. Is this about having too FEW skillpoints or too MANY skillpoints? Because last time I checked, they don't let you job advance only when you haven't spent all the pre-4thjob SPs. If you purchase the CS 3rd job skillbooks and somehow wind up with 1 too many skillpoints, you just raped yourself, but if you don't purchase, you'll have even more points left over. Solution? Non-CS skillbooks.

Unless all that was just a bluff that I fantasized for my own amusement during the boredom period.

It's 17 SP's too many:

From 1st to 3rd+ job:

You get:
120-10 = 110 * 3 = 330 SP to spend

You can spend only 313 SP on all skills available (without using mastery books)

Ending up with 17 SP's at lvl120 you can not spend anywhere...

But maybe something else is happening, we'll have to wait for Rigumaro's reply on how many SP's he has left at lvl120, and if he used any Mastery Books yet...
