We've done several hundred hours of multivariate testing (think: test record) in 2023 and have come several conclusions. One of them is: you aren't measuring what you THINK you are measuring!I have almost all the test records ever made, and yes there’s no way they’re all “the same”. I’m coming around to your (and Wally’s, RIP) way of thinking, that if it can be accurately assessed in physical terms, without a record, and it can be corrected using physical methods, do it that way first.
