What is your line speed?
I assume 2Mbps?
If you get about 1.7Mbps on speedtest, you should get about 40kB/s.
But I already said that in my opinion those figures in the CZ are not correct, because on P2P I received 50% less on the 6.25% figure. I only received 10 - 13kB/s instead of 26kB/s on a 4Mbps line.
I'm working on figures achieved in speedtests.
I have disregarded speed test results as I have never achieved a consistent result on 2mb. When unshaped, the line runs full speed on torrents and normal downloads.
It's a bit of a slap in face that AH can give all their capped users extra bandwith, whilst squeezing the life out of its uncapped customers.
