My doubt is, having 2 simultaneous connections making deliveries to the same domain, this process you described happens in each simultaneous connection (doubling the delivery rate) or all simultaneous connections delivering to the same domain coordinate so, no matter how many simultaneous connections I have to the same domain, only one delivery will occur each N seconds?
