That's using the average US electricity cost as the cost basis for the calculations. http://www.eia.gov/electricity/monthly/epm_table_grapher.cfm?t=epmt_5_6_a
(I think I've got the hashrate equivalents and electricity consumption figures right - please, correct me if I'm wrong.)
ASIC allows you to profit at up to 20 times less electric cost, which means that price can go as low as ~10 satoshi in the case of DOGE and the ASIC would still be looking at breakeven (the GPU DOGE miner needs a price of ~200 satoshi to break even).
MYR could go as low as ~15 satoshi with the ASIC still keeping its head above water.
So if I understand it right, it would be better if Sha/scrypt algo's diff would rise much faster compared to GPU/CPU algos. So it would fix the problem we have now. ASICs would get much less coins in the same period of time.
In other hand, if ASICs will leave (because of no profit), what will happen to our blockchain? It would decrease quantity of miners drastically... But the price should rise and inflation effect should be much smaller...
The fact that the sites are not considered to be profit-making parameters Asik's the reason really.
