I think the smartest thing for you to do is to read the lib/progress.c source
code and see all these details yourself.

The average speed that curl shows is the average speed so far during the
entire transfer. Going down 2 out of 1800 is about a tenth of a percent. It's
not like it is a significant amount that I find it worth to lose a lot of
sleep over. And I will most likely close your just filed bug report saying
exactly this. I doubt anyone feels like chasing for this problem that might
not even be a problem.
