Why are progress bars when installing or downloading software so wildly inaccurate? Why is it difficult to estimate this?
Imagine driving a long distance on the road. Your destination is 160 miles away, so you drive along the highway at about 80mph and figure that you need about 2hours total. Then, in the middle of that 160mi, the road gets very bad (you had no chance of knowing that) so you can drive only 50mph.
The Short Answer
Imagine driving a long distance on the road. Your destination is 160 miles away, so you drive along the highway at about 80mph and figure that you need about 2hours total. Then, in the middle of that 160mi, the road gets very bad (you had no chance of knowing that) so you can drive only 50mph. You don't know if the road stays that bad, so you just assume that and calculate 1.5hours until your arrival. But fortunately the road gets better after a few miles, you can drive full speed again and your estimated time of arrival changes again. Downloading a file is the same: If the current speed changes due to something you can't know beforehand, you have to recalculate the remaining time. This means sometimes that the estimated time jumps around a lot.
