ok.. so I have a question about the minimum 512 difficulty on stratum...
How does that affect things when we are mining a coin with below 512 difficulty? For example, lets say we are mining Xcoin with a current difficulty of 400. I find a hash with difficulty 450, but it doesn't get sent cuz stratum is only sending 512+. Does that mean the pool just missed out on finding a block?
I'm hoping this is just a case of Difficulty does not exactly correlate to difficulty..
You are correct, they are two very different measures. A difficulty 1 coin has an average number of hashes to solve of 2^32 (4.3 million). A share difficulty of 1 (which you wouldn't submit, since our minimum is 512) has an average number of hashes of 2^16 (65k). They're just orders of magnitude different. I'm honestly not sure why the same descriptive word was originally chosen for both, but it was
As a point of comparison,
Does anyone know what the BTC/Mhash rate is if one were to mine only LTC and immediately convert?
Right now (~3600 difficulty), you're looking at 0.00596, at perfect efficiency (no orphans, perfect luck, etc).
