I think you are partly wrong. The Herbie and the BA are both siphon drains so with the same size pipe they can handle the same flow. The BA adds the emergency drain, but also uses the second drain as a trickle (which is how many people run their Herbie). The trickle set up means that you shouldn't have to adjust the siphon drain gate valve once you have it tuned. That trickle can take more or less as minor variations change the flow through the main line.
