My exchange now gives me a profile of 88.2% of my current sync speed. Although I have not checked precisely how quickly this is effective, it does appear to be pretty quick. Are these changes reflected in an Idnet connection so that if a blip on my line gives me a low IP and by a re sync I can restore it, I will not have to wait days for my download speed to recover?
The profile controls the d/l speed, it should follow automatically. Large changes in sync speed recover more quickly than small ones.
