Unfortunately, no.  Since Yacoin does not have a consistent method for GPU mining, it is a tough comparison with all of the other coins that do.  In other words, I guess if I am only mining on my CPU, it is interesting whether Yacoin is more profitable than BTC, but I think the real question is if it is profitable at all (taking into account energy costs).  Those calcs are more typical of wheretomine.com which has the dollar rates.  

FYI - it is on an exchange (Cryptsy).
