So does everyone get only ~80% regular scrypt hashrates (i.e. like how vertcoin is ~50%), or does the ybcminer just take some tweaking vs cgminer regular scrypt settings..?

i see people before with crazy 3-7MH/sec per GPU, i'm guessing the N factor has changed significantly in the last ~2-3 weeks..?

this is with the gpu-miner/ybcminer linked in OP
