Forums Scripts & Popups calculate DCC time left

Hi!
How can one calculate the time left for a DCC transfer (send or get) to be completed?

I've tryed these two codes, alternately, for the 1st DCC Get:

$duration($calc(($get(1).size - $get(1).rcvd) / ($get(1).rcvd / $get(1).secs)))

$duration($calc(($get(1).size - $get(1).rcvd) / $get(1).cps))

I've used a timer, with both codes above, however i've noticed they do not display the same duration as presented on mIRC's DCC transfer window.

Can someone tell me what's wrong?

Thanks in advance!!

This may mean that mirc does not calculate the time left based on the current speed of the transfer. It may follow a lot of different algorithms. One of them could be based on average speed:

time left = time elapsed * (remaining bytes / received bytes)

in scripting terms this would be
$calc($get(1).secs * ($get(1).size - $get(1).rcvd) / $get(1).rcvd)

which can be simplified to
$calc($get(1).secs * ($get(1).size / $get(1).rcvd - 1))

and, in turn, to this:
$calc($get(1).secs * (100 / $get(1).pc - 1))
