why loading bars jump around instead of smoothly increasing percent?

You have to drive to the store, buy milk, then drive back. Let’s make a loading bar. You start at 0%.

Driving to the store goes pretty smoothly but there’s normal traffic. 0%… 10%… 20%… 30%… You get there. 33% done.

You go inside… 40%… find the milk… 50%… get in line… 60%… oh wait, the lady at the front is paying in pennies. I guess still 60%. Okay she’s gone, but the guy after her had his credit card declined. I guess 62%? Oh now they need a manager. 63% maybe? Okay finally it’s done, 66%.

There’s absolutely zero traffic and you make every light on the way home. 80%, 100%.

Of course, if you knew ahead of time how long each segment would take, you could have accurately predicted your real percentage in terms of time, but there’s no way to know ahead of time.
