Although best share doesn't matter when solo mining its still fun to see how close I come.
I wonder if other people with 1th miners move to other pools thinking that since the best share always reports 0 that its not working correctly.
Or as another option, if you do restart the pool again maybe it would be possible to set the default difficulty to 1023?
When I eventually restart the pool it will show best share as well in the user/worker stats.
