During the installation of LibreOffice on Windows, the progress bar which is supposed to show the progress of the installation starts from 0 multiple times, as files are copied, the registry is modified etc. It would be good to make sure it never resets, so the progress bar can actually fulfill its function of showing installation progress. (Otherwise, it is useless to most end users since they don't know how many tasks the installer does.) The best way to go about this is probably to time several installations and then average out how much time each task took.

Ouch. In any case, I have checked again and it actually resets just once (but it stops for some time at the end). FTR, here are the measurements: 14 s – reset (note that's 14 seconds including clicking away a UAC prompt) 80 s – bar is at the finish but doesn't reset 94 s – installation finished
