Re: profitability
I am looking at Scrypt only - my concern isn't that I was earning X last week and I am earning Y this week, but the actual last 24h earnings are barely 1/2 of the current estimate - I know there can be variation but it is usually about right, Also the individual coins are all showing between 2 and 3 mBTC/GH/Day

With 500Mhs I should be getting about 0.08 LTC (whattomine and manual calcs), which is currently at 0.016 BTC (current @ Bittrex) so this should come come out around 0.00128 BTC/24h.

Over the last 26 hours I have made 0.00055 BTC which is less than 1/2 what I could get by mining LTC straight. 

I don't know what the issue is but there seems to be one. it MAY be that the pool keeps dropping large amounts of hash onto LTC, but not enough to get a block (last LTC block was 30h), so it would seem sensible to drop LTC from the coin list as we don't have enough hash to mine it effectively.
