Quick question regarding cgminer. I reinstalled BAMT today on my USB and let the default settings run which gave me a +20khash/s boost per card. However, I did notice over the day today that I get like 10% rejection ratio, which with my old settings and lower hash I was much lower on rejects. Not sure if that is something with todays mining in general or just me. Couple things I was wondering about however.

Do you guys use expiry in your configuration and if so, what value? I know the default is 120, while mine is set to 30. How about the other ones like
scan-time
retry-pause
queue
sharethreads ?

Thanks!
