Organizer, not sure if you saw it but he changed up a small bit on the Dual MODs:

"If your account contains Dual MODs and BTC is chosen as payment method, the Dual MODs mode will be set to most profitable coin minable with MODs, which will be converted to BTC with 5% extra over day average at Cryptsy and payment will be sent to SHA-256 address (only if SHA-256 address is filled).
If your account contains Dual MODs and LTC is chosen as payment method, the Dual MODs mode will be set to most profitable coin minable with MODs, which will be converted to BTC with 5% extra over day average at Cryptsy, then to LTC and payment will be sent to Scrypt address (requires to have a Litecoin address)."

So no need to pick which coin to mine it pays out the most profitable.  This may change your calc some.
