i hate to be a spoil sport but this is why I did not participate in this round of tests, I find that the means of testing isn't accurate at all.
For instance I experience the internet with multithreading but I can't run those tests with multithreading, it obviously seems to use the Telkom ADSL test, which is worrying because it shows the tests were planned by people with very little network or programming experience. You see the telkom test is just done with java script, it initiates a simple timer then you download what you think is 500KB (a long html comment) then after that you get the java script that stops the timer and works out the speed... there are two problems with this, firstly the data you download after the javascript timer is started is less than 500KB so it stands to reason the results are off and secondly because it is a large html page firefox will download it in 4 parts minimum if network pipelinin is set to true. So this means that last bit of javascript can be executed before you have downloaded the entire page.
I fear the same thing will happen with this round of testing that happened last time, that is a clear bias towards adsl, which is fine, more people use adsl... but it does not give the test credibility.
The testing methods will obviously favour lower bandwidth connections, thats just because its easier to hit 30KB/s all the time than it is to his true 1mbit all the time, without multithread. If iburst can get 80KB/s on a single thread with the tcpIQ test for example it will be weighed less than adsl 386 (or whatever it is) because it will get 30KB/s all the time, so in the end myadsl 384 looks more stable because nobody factors in the fact that it is too slow to need multithread anyway.
Couple that with the fact you're looking for more iburst testers a day before the tests stop, that just shows there isn't a large enough sample to rate iburst anyway.
And even though iburst is faster than 1mbit adsl it will come up shorter in these tests... my prediction is it will be adsl 192, 384, 512 then 1mbit and then iburst and lastly sentech in that order.
