just an info from me..

i used to test v6, and it has a lot rejected shares, so i stop using it,
v7 never got working, some error popup up after initialization..
v8 is ok, but i see s lot of rejected shares, didn't compare a real number with other miners but it seams big....

now been running bminer for 14h and tih has about 1.5% rejects shares against accepted shares.  thats a really big amount... i used to test dstm for some time and i guess it was like 0.99%... 0.98%   for running like 24h or so...   this miner v6 ..8...  has a large number of rejection.   

didn't compare it on pool, but it can be just worse that what console says.
