I can understand the /48 and /56 options (for corporate and residential 
respectively), but I don't really get the /52 and /60. What is the cost 
difference to the ISP that warrants a different end user price for these 
services, and isn't it just an extra cost to switch the user between these 
services (reprovisioning) when their needs change?

I believe in the "give 99% of the people what just works in the long run 
if it doesn't cost me extra" method, and I see it as sompler operationally 
to just offer /56 to residential users instead of /60 AND /56.
