I'm very easy to convince if your argument has substance and is based in fact, but so far the only arguments I've seen are merely statements that I am wrong or, even less persuasive, that I am an idiot. Since I've designed entire drive systems for locomotives for my day job I'm unlikely to be convinced I'm an idiot just because some random dude on the internet says so.

Again, I am more than happy to change my testing methodology if a reasonable explanation can be given as to how it could be so flawed it would result in a 30% difference in coins earned on two consecutive days based on reported hashrate and average difficulty on minethecoin.com (not a snapshot of earnings from whattomine.com).

That said, the official Trezarcoin pool does allow mining with a fixed difficulty but adding a second account from the same IP address appears to be blocked by default - I've already sent an email to the support address saying I want to add a second account so I can test miners concurrently but no response so far. Thus I can at least try jugger1028's suggestion to count the number of shares earned with a fixed difficulty for x period of time with hsrminer, then compare that by mining with ccminer for the same period of time/same difficulty; the length of time wasn't specified, but based on the average time to find a block on pool.trezarcoin.com it seems that 12 hours per miner should be sufficient.

So, if that is acceptable I will proceed with the test, and if the results contradict my earlier findings I will edit my previous posts to warn that I got different results with a different test methodology because I don't have a particular axe to grind here.
