TRC difficulty
often there is a significant difference between TRC difficulty on Coinotron page and the well known
http://dustcoin.com/miningSo when I mine at Coinotron at any given point in time which difficulty is the right one? What am I mining against? If dustcoin says 500%+ and Coinotron homepage says 60% what the @#%$!! should I do?

TRC changes even faster - my site averages out for the given hour to reflect current difficulty, but I'd be weary enough of TRC's difficulty as it is.
