Question about the Argent Dramaturge PCl and the Silver Raven subset of the PCl

[Finite_Fellow]

In the rules of the Argent Dramaturge PCl there are the feats related to the silver raven order (Diva Style, Diva Strike, and Diva Advance) that all have prerequisites of having a certain base attack bonus or an equivalent bard level. My question is if I take Argent Dramaturge as my prestige class 7th level when I meet the requirements, does each level of Argent Dramaturge also fulfill one level bard for the sake of these feats? The reason I ask is because for Diva Advance you would need a bard level of 11 which would make it so you would never finish the prestige class by level 20 despite being fully invested in the class.

Thanks for any help in advance!

Diva Advance: 'base attack bonus +11 or bard level 11th.' The prestige class doesn't help for the bard level but will for BAB. Or you could ask your GM for a house rule, but it doesn't stack for bard levels RAW.
