Testnet Bitcoin Generation Time
What is a typical winning block (I get coins) generation time when running on testnet.


I plugged your rig statistics into this calculator, and I find that you should be getting 60 blocks a day at difficulty 1. Seems to be oscillating between 1 and 42 at the moment. Maybe you should try running for longer.


  How can I be sure that I'm actually mining, not that I'm just computing useless hash after useless hash thats getting sent to a black hole somewhere?


The standard client is pretty good about not even trying to generate when it's not connected. Perhaps you could join a testnet pool? :)
