What kind of speed changes did you see in this process? ie the before/middle/after figures?
It is annoying trying to track these things without the main tools available, isn't it. Everything based on the profile value from a BT speedtest... which you can only run once an hour. No way of checking of your line's environment is changing over the course of a day...
