I recall during my CS studies that predicting loading bars with 100% accuracy is literally impossible. Something about the only way to predict it was to actually perform the action and then report back to the user.
Did some quick Googling to find a paper or article on this and nothing turned up, unfortunately.
Is that It’s an asynchronous operation and you need to send messages in the form of events back to the UI thread. But it’s difficult to predict how much of the total percentage of progress you just finished in the small part it’s doing, since every part is doing something different or longer-taking. So it’ll jump and won’t be steady. Or, you make a fake one that goes steady and shows down at the end, or something similar. So, fake. :)
what do you mean?, ive never heard of loading bars being faked and never had a reason to doubt them, they do what they say. Was i the only one not in on this info?
Ok, i get it now. Its not fake but rather not accurate. I thought this post meant the loading bars were just made to look like they were doing something, but i do get that sometimes the bar gets stuck on 50% for a while and rushes to 100%. it still is showing the loading % just not accurately
To the surprise of absolutely nobody….
Loading bars anywhere are an approximation at best.

I’m sorry to burst your bubble 😅.
Rather than try to explain it myself, here’s a post from someone else that does a decent job: https://www.maketecheasier.com/how-progress-bars-work/
