I see mention of people dipping Maneuver Master fairly often in order to get the flurry of maneuvers ability. I'm interested in doing this but the wording on the ability seems to suggest that it would be suboptimal, using only monk level in place of BAB for CMB and not adding monk level to BAB from other classes.

Flurry of Maneuvers:
"The maneuver master uses his monk level in place of his base attack bonus to determine his CMB for the bonus maneuvers."

This is in comparison to the wording for the normal monk Flurry of Blows:
"For the purpose of these attacks, the monk's base attack bonus from his monk class levels is equal to his monk level."

Is there some obscure ruling I'm missing that is making this dip worthwhile?
