So my RAF is still active, though I think I leveled my 4 new toons from 1 to 85 before 4.2.
Does the RAF remember all the dings till 80, or only the ones till 60 ?

Leveling one toon from 1 to 80 gave my slave toons 40 level grants, that times 4 makes 160 level grants together. I have linked RAF like (A-B, A-C, A-D, A-E)

If I now make DK on account A, and then have B granting 25 levels to him, that would do 55 to 80 aye?
Then I would move the fresh DK to account E and create a new one on A account, grant levels, move A to D, rinse repeat..

In the end I should have five lvl 80 DKs after 125 level granting and still having 35 free level grants available. Did I get this right?
