Thanks Con. I realized on the road and you answered before I could edit, but they claimed it was the stock hashfast driver, not cgminer. Since hashrate is calculated in cgminer.c and not driver-hashfast.c, I suppose they could have been using a stock hf driver but modded cgminer and not technically been lying.
The stock hashfast driver was the same driver as mine. They only changed the display output and I can tell from the screenshot that that is not hashfast's build anyway.
