How about we just look at the ETA that it gives us.

Because as soon as you look your download speed comes tumbling down, especially on Steam :(

I love these posts for ideas that already exist. "Guys, I've created a formula to determine how fast your car is going
based on the distance between 2 trees beside the road and..."

Are you the guy who coded Windows copy dialogue

here's mine
open download
look at download speed
dont steal my forumla pls

5.0 Gb = 5000.0 Mb = 5000000.0 Kb

this cant be right

OP is a mathematical genius.

[QUOTE=Satane;34790971]this cant be right[/QUOTE]
its not.
1024Mb = 1Gb
5Gb = 5120Mb

For steam, Look at the time left, Double it

[QUOTE=areolop;34791765]its not.
1024Mb = 1Gb
5Gb = 5120Mb[/QUOTE]
Those are Mibibits and Gibibits. The symbols for units of bits as a product of a power of 2 have the letter i in them to differentiate from the units using normal SI prefixes. So, 1 Gib = 1024 Mib, but 1 Gb = 1000 Mb

ETA should be given in fortnights.

I just usually take about thirty minutes off and it's pretty accurate for me.

I use this simple method:
If its big, it takes a long time.
If its small, it takes a little time.

Time remaining: A while.

its pretty easy to remember. 4gb takes ~1 hour at 1 mb/s

Elementary, dear Watson.

Finally upgraded to BT Infinity. 4.0 mb/s. Oh Yeah.

More like 1 MB/s.:eng101:

Four milibits per second? I can achieve a faster bitrate by farting in morse code.

Thanks for this information. But to be honest I normally go by "Estimated Time left" I know it might not always be 100% accurate, but it's close enough that I don't really mind.
It also depends on the download, for instance something that's under 1gb I know will probably download under about 10 minutes at most. So I just go grab a snack and come back to find it finished downloading.

[QUOTE=Rad McCool;34779166]TLDR:
Take the file size.
Divide by the average download speed.
Done!
Not only is this method much simpler, but it also actually gives you the right time. [img]http://www.facepunch.com/fp/ratings/funny2.png[/img][/QUOTE]
You're forgetting that finding the average is the key to this. You could of course sample the download data every second, but you'll eventually come across some stray readings that will manipulate your average, so you'll have to give the samples further in the past less weight when you find your average.

it's not even a formula, it's an algorithm

I kinda not give a shit then watch Breaking Bad as it downloads/installs.

Time remaining: Fucking chill out and wait a while life is too short to try and waste time doing math

I came in here expecting a formula, I found a list of steps and no formula.
And to add to the horror: they are wrong.

(total file size - current download size) / (current download size / current time downloading) = approximate time remaining
i accept paypal and nobel prizes

lol by the time you finish writing out the formula the download will be done

I just start the download and do something else for the next 2-3 hours, isn't it simple?

If I am trying to do this the download will be done when im done.
