Funny, I have always wondered what these numbers mean :)
The name definitely is misleading :/

Unfortunately I cannot get numbers for Ubuntu.
I have tried several times and just starting installer causes system
freeze after some time. It is either out-of-memory or hardware problem.
I will investigate it tomorrow.

BTW. I have noticed "debconf-copydb" processes running at installer
startup, the same which cause lag in Kubuntu installer, only running at
different stage.
