Actually I think I did the math wrong in the first post.
For every two levels gained, you can boost one level.

Since we start at 1st level and not level 0...
And RAF bonuses stop at 60th.
We have [60 - 1] / 2 = 29.5
Since leveling to 61st does not gain us the extra 0.5 levels needed...

A toon leveled from 1st to 59th (58 levels gained), has the ability to grant 29 levels.
Even though going from 59th to 60th gains us nothing as far as granting another level...
It does give us one more level at 3x exp's and also allows us to boost 59th level toons.
