I think that scrypt-n profitability should be shown as profit to 450khs (as CoinWars do) because same GPU makes about little less than half the hashrate, so 250% 'LTC profitability' is nonsense, as you get only half hashrate from equipment that do 1MHs in scrypt.

Maybe two values should be shown, profitability compared to VTC at 1MHs and profitability compared to LTC at 450kHs.
