with LCC challenges, you have to have a verification method otherwise it is too open to cheating. good faith works over at XS in our thread, but on HWBot? come on. one way is to include in submission rules a digital photo of the benchmark mid stride (loop 20 or something) with CPU-Z open. all that would be required is a photo of the run at loop 20, with the iteration times being visible as well as CPU-Z. it is harder to photoshop a photo...still possible i guess but at least a deterrent.
yes having CPU-Z open will hinder the run, but if everyone has to have CPU-Z open for the run, it is still fair.
just my $.02
