Thanks for you comments though George, just sorry that you gained nothing from the results.
Actually. I've gained a lot from these results and the other tests. As I said, I'm grateful for all the work put in. IMHO this is the best thing going on within the forum at present, and for some time.
Despite my initial doubts, these group tests seem very worthwhile, unlike many other 'reports' reaching the forum on other threads, which strike me as random observations with no conclusion, or of much value at all. Just fog, like data overload, so we can't see the wood for the trees.
