Released 0.9.10 beta:
- now videocards sorted by BusID
- added luck calculation(need testing, experimental feature)
- fixed crash when logging and --print-full is used
- few more checks for scratchpad fails(also in some cases miner will reconnect if it failed and only then redownload it if this not solve the problem, need testing)
Downloaded, 1rst, what you added is not luck, but effort, luck never is more than 99.9% and can be negative

2nd, I noticed a hash drop on the first seconds with this version...
And if you divide 100 for the average effort, you'll get the factor from wich you can get the estimated pool side hashrate
