as an addendum Marc I have found that the people make changes or tweaks to their systems the results are always followed with great comments about what they hear. IOW they do an A-B test. What they don't do is an A-B-A test to truly know what the changes are and are very resistant to doing such. That takes them down the rabbit hole and always seem to be chasing their tails to correct a change from something they did rather than just saying, the changes were not always positive
My mantra has always been , "did you hear something better or just something different? If it was something better then how so?" That involves an A-B-A test Marc
Ive done it 8 times. Read the reviews on the product Marc before you try to fan some flames
I prefer just a B-A. Put something new in for two weeks. Switch back. You’ll know in moments if you’re keeping the new thing.
