At the beginning there is 2 minutes, after 25% of installation there is 4
minutes. The whole installation takes about 14 minutes (at the end) in real
(typical desktop installation). So there is something wrong. Anaconda used to
count almost precisely.

This has been an issue for many many releases. The estimate is just that. As the
install goes along the estimate will be closer. There are operations going on
beyond copying files to disk that make the simple projection of time incorrect.
