said by ExoticFish:Let me rephrase that... Powerboost will reappear on business accounts after the initial "boost" whereas on residential accounts it's only available for the first part of a download.
That's what I remember reading somewhere anyway.
The only difference I've noticed with PowerBoost on business is that it's basically uncapped. For example, residential 25/4 Blast hits about 35/6 with PB. I have business 22/5 and just now it hit 93/20. Other than that, it's the same. It basically looks like the picture mrschultz02 posted above, just with a much higher initial spike.
