Even though I have really gotten the solo mining topic into rolling, I have a basic question about solo mining:

Do you mine for hours on the same block or do you start every time you see "stratum detected new block" - difficulty set to 25, a new block? This is especially confusing, as you see on the 5th line of cgminer:


According to that your miner would be updated when a new block is found, and your miner starts working on the next block.

But on the other hand, if your miners are working for hours on one block, how does the changing difficulty affect you? And if this is the case, should you restart your cgminer after a certain amount of hours if your miner was not successful, so you try out on a different block?

I know it is kind of embarrassing to ask that question so "late in the game".
