No, it's impossible. The Up IP Profile is wrong.
As a rule of thumb for both Down & Up:
- IP Profile = 88.2% Sync
- Throughput ~= 83% Sync
EDIT: Generally I only use the BT Tester to get the Down IPP and even then almost invariable I don't need to go there as I can just calculate it for my reliable line. It's really only useful for users who suspect their IPP may have been capped. Get Throughputs from TBB speedtest.
