Due to the extremely low velocity necessary to achieve critical Reynolds number, 'flow speed' has nothing to do with body geometry effects until the local MACH number is transonic, up around 250-mph ( 403 km/h )

And yes, it is the horizontal component of the aft-body, as a fraction of total body length which determines the maximum angle which will support attached flow, according to Buchheim et al..
