Well, obviously the bench doesn't appear to being used for less than noble purposes like so many are in order to generate profit. But it does help when even the hobbyist user standardizes their bench so that when numbers are produced, and not just for apples to apples comparison. When you have results that are wildly different than what a standard procedure shows, then it's also unlikely the bench is maintaining a truly linear airflow. I'm curious to see what the calibration plates show on that aspect, too. But hoping the best for you with it, and please keep us posted on your findings. I'm encouraged by anyone who builds their own flow benches because that's another "someday" on my project list at present.
