Let me make an admission to your side. There isn’t any good test data (or as you put it evidence).
but we know people come out of isotek demos impressed, and by credibility of extending that to tests of many more people, lots will probably do. In fact it would be a 2 percent failure rate on ellis’ isotek demo, by extrapolation, however reliable doing that is.
so if we took that as a basis of saying doing that isotek test for a 1000 people, and our results showed many people hearing changes, which could expect on 49 people, where does this leave us in explaining what’s going on.
Thats where I come at this from, credibility - because it’s very very credible. I’ve heard that change with my own ears, as have many others. Assuming you just come at it from asking for evidence, without hearing, where does that leave you in trying to understand it Pedro. Absolutely nowhere. Again you have failed before you’ve started.
