Hi, Sal002
Your JSON API is just what I was looking for!
I plan to implement miner profitability grouping in the next version of my
Bitcoin Miners in Tray GUI and was looking for a convenient place to read profitability info from. I came across you site in a round-about way through dustcoin's thread

Could you, please, tell me what is the difference between "ratio" and "adjustedratio" in the JSON object?
I'll send you a donation once I have implemented miner profitability grouping in my program.
Adjusted profitability is the profitability adjusted for what I anticipate will be stales (as compared to the base currency). From some testing, faster block coins have more stales, so this is an attempt to smooth this out.
