Yes but that means your coins are worth twice as much to you, since you have paid twice as much electricity for them.

Unfortunately that's not happening, FTC is grossly undervalued on the exchanges atm. remember it takes the same amount of electricity per block as LTC, the only difference is the block yields 4 x more coins than an LTC block does, therefore FTC should be selling for LTC/4 and it most certainly isn't.
You didn't adjust for difficulty. The easier it is to mine the less electricity it takes to mine, so if its difficulty is half litecoin's thats another factor of 1/2 to apply to this imagine parity-price you are trying to calculate.
At the same difficulty yes you get four times as many coins for the same amount of electricity. At half the difficulty you eight times as many coins, and so on.
The same happens with GRouPcoin, it makes 50 coins per block, DeVCoin makes 50,000 per block, so in the long run, if ever they both had the same difficulty, you might expect GRouPcoins to basically function as 1000-devcoin denomination coins.
But as the difficulties are very different, it has actually been valued less than one devcoin per groupcoin for quite a while, though that looks like it might change soon.
