Yes that is correct.

I don't need a very high precision but I need a value that looks alright.
Imagine I'm downloading a file at 1600kb/s which in this case is the maximum
for the used connection.
Now I'm starting another download. What happens is that the speed is divided to
both downloads.
On my try with the average speed this scenario didn't work very good.
I got a total speed that was much about the possibility for the used connection.
But I have to look at it again to be sure if it is not me who made a mistake.
I should mention that I asked for the average speed before the download was
finished.
(Is this legal or doesn't it work for a not finished download?)

I'll take a look at it back again.
But maybe I'm just doing something else wrong. Lets assume this is how my
callback looks like (I'm using C++ Classes so the static is needed):
static int callback(char *data, unsigned int size, unsigned int nmemb, void
*ptr);
So the total size of data that had been received is (size * nmemb).
So inside the function I'm checking how much time passed.
The time that had been passed I convert into seconds and divide it by (size *
nmemb) to get the download speed.
Is it right that way? The size of received that had been constant while
testing. Something around ~16000.
Thanks :-)
