Well, I expect it goes like this for figuring out a lower
bound estimate . . .

) The overall trend is that the Pkg/Hour rate is decreasing
  as more builds complete for build of main-* (here main-amd64).

) This results in the Pkg/Hour figure shown normally being
  larger than the final value, continuing to decrease as the
  overall build sequence progresses.

) When I just looked: 8851 Remaining and 108 Pkgs/Hour were shown.

) So a likely underestimate would be 8851*(1Hr/108Pkgs)+,
  So 81.9+ Hours: 3.4+ days

) Aug-29 19:12:?? UTC + 3.4+ days is Sep-01 19:12:?? UTC + 0.4+ days,
  which is about Sep-01 19:12:?? UTC + 10 Hours.

) So crudely, still likely an underestimate: Sep-02 05:00:00+ UTC

But I'll note that the Impulse (the prior 10 min scaled out to
an hour as if the rate was fixed) seems to be showing figures in
the 40s through 60s. That would scale out to more like, say, 160
Hours instead of around 80 Hours more.


Note: Before the first 10 min have gone by, Impulse scales
differently --and does not show for the first 2 minutes.
