How come speeds like 29K in a 56k modem?

[~*McoreD*~]

This is something I noticesd for while. You know, sometimes when I download files by a 56k (=7K) modem, I get initial speeds like 29K! and it reduces 27K, 25K, 19K, 17K, 11K, 6K, 5K like that and then stays in an average constant speed around 5K. The question I have is, how come the initial speed rises upto more than 7K?

Because the 56k modem, afaik can handle maximum of 7K of data, I feel it is impossible that to happen. I have seen many times that happens - starts from like 25K and then reduces down to below 7K. I can't believe that happens! I am lost...

Do you guys know why?

I think it may be that when you click a download , it actually starts and is buffered while you select the storage location of filename , as the buffer is stored the average speed is recalculated hence the rapid drop in speed.
I have noticed it only with IEplorer downloads , when running thru a download manager the speed seems more constant.

Sometimes,

I hit a 14 or higher score with Flashget too But the average is about 5k with my 56k modem
