I've seen no absolute proof that Cathar ever quantified a difference in performance (other than a rough .5C, well within his margin of error) with his new block over his ww block. If there is a performance increase the source of the increase has not been pinpointed (witness Les's argument on bp flatness from machining differences recently). Cathar's two blocks are a perfect example of why resolution and accuracy are needed for any answers. I seriously doubt he could quantify a difference with his homestyle test equiptment. I believe that a difference has been noted through higher overclocks, but chips sometimes do overclock differently over time (not diffinitive). His block has so many variables to it that I do not see how he could have optimized them all together without SEEING a changed variables effect. That being said there is nothing wrong with applying ones theories through invention but even trial and error has its limits when you cannot identify an error.
