I used a Lumia 1020 running the +Stopwatch+Timer app to record the total elapsed time at various stages of the upgrade process. Every time I took a photo of the upgrade screen, I took another snapshot of the stopwatch app.

The stopwatch timer was started at the same exact moment the Start the upgrade now button was clicked.
