Not too pleased as if I download over 3gb in peak times my 20mb connection will be reduced 75% to 5mb for 4 hours.
It's a very generous throttle control. I've never downloaded 3gb in one day let alone during peak times. The most I've ever done in one day was a linux iso dvd image (just over 2gb).
I can't see anyone really complaining about that limit. Surely 99.9% of users would never ever exceed 3gb download during peak times. In fact most would never exceed 1gb a day.
