IIRC the time period for a rise on Kitz is out of date, but the table of speeds/profiles is correct.
Fow a large percenatge rise, which yours looks like without the full figures, it can be a few hours to a couple of days. I expect overnight stands a chance. What profile you get all depends on the current connection speed, as line faults can affect that over the medium term as well.
Small jumps can take 5 days to get the profile rise.
Assuming you now have a decent connection speed you don't need to do anything more. The profile rises in the background and download speeds suddenly jump.
