Eh, it took SpaceX several years to scale to that sort of launch cadence. I certainly wouldn't expect Old Space to miraculously reach a flight every other week within a year.

> why ULA went with BO has never really made sense can anyone tell me why?

Aerojet's AR1 engine was way behind in development. In short, they didn't want to design it unless someone else was paying for it and that made development drag out. BO, on the other hand, was building the BE-4 on its own dime regardless of whether someone else was interested in buying them. Aerojet basically has no ambition as a company.
