Shouldn't that largely depend on server implementation? Server implements ack handling poorly vs Server implements it OK will have very different throughput for the same ack frequency from the same peer, assuming everything else equal.

And that's why using a specific recommendation in the draft is tricky. This is a receiver behavior, but it's the sender that knows what's the best way to do it.
