lol, luck = 100% would be getting a share without doing any hashes, so it's impossible 
nah, I don't agree 
Today after donation mining I got some shares rejected because "Duplicate Share":

This one is bad, will check my code for thread safeness more. How long it was, till new job or just his three shares?https://image.ibb.co/gD7tGo/error_Wild_Rig.png
I got those 3 duplied ones, and then more than 1 minute without shares, so I just restarted the app
