I'll ignore your an eye for an eye... and offer a clarification:
I have seen the same density formula question asked several times over the last couple of years... and the answer has always been that there isn't one. That doesn't mean you or someone else can't come up with one... but due to the complexities previously mentioned, I think it has discouraged people from trying.
With regards to me ignoring your points or me having a lack understanding of them, I disagree.
I have about 20 or so containers on 2 physical hosts... and their resource uses vary greatly even though they are all the same Linux distribution (CentOS) running on the same host node distribution (RHEL and CentOS). They vary from a simple webserver with no additional system accounts, to a system that runs a telnet bbs that sometimes has a number of online users, to Zimbra Collaboration Suite which is an enormous system which includes a fantastic but very bloated Java server app and says that it should always be run on a dedicated server.
Anyhoo, I must admit that I've had a lot different situation than you where you want a lot of all-the-same containers. I could be mistaken, don't think I am... but feel free to come back and correct me if you find what you are looking for. If there is a useful formula for container density calculation, I'd like to know what it is too.
