If the pool is designed to always mine the most profitable coin and the coin that the profitability is based on is litecoin then in theory we should never go below litecoins profitability as when litecoin is the most profitable then we are mining that
1. I think you should keep in mind that mining a coin which is more profitable then LTC do not necessarily mean that the coin will be sold
with more profit to LTC.
2. There are more pools doing the same way (with also a lot of hashpower) and trying to sell the coins!
I think the best way is dividing clevermining in regional server (US/Europe/Asia/Afrika.....) and let this 'little' pools mining different coins
So 3-4 most profitable coins are mined.
just my 2 cent and stay tuned
btw: Tuned my rigs to sgminer with experimental kernel ===> hashpower up from 2.69MH/s to 2.71MH/s but WU: from 2.35M to 2.5M
and 1% rejects for 4hours........(i keep an eye on it)
@Terk keep on.........
