lol...I knew my odds were practically zero but it's nice to see the math which proves it. Those odds are lower than I thought. Still, I'm running a full node for several reasons, only one of which is solo mining. My "rig" is 3 block erupters, so the amount of electricity being used exclusively for mining is negligible. I've had the block erupters for years so I thought since I'm running a node I might as well put them to work. 

Now if they do find a block I'll have more appreciation for such an extremely unlikely event
