Tried the unit again today. Set it up 25 feet from the front of the shooting bench. First up was a .204 Ruger that has been rock solid consistent, and the two rounds over the chrony were pretty much spot on. Next up was my 222 Remington which was the rifle I had really goofy results with before. The first few rounds were looking like they were in the ball park. Then velocities displayed jumped about 100 fps, and became more erratic. So, a deer rifle (243) was next. First two rounds the velocities were similar to several different range sessions a few months ago. Then sure enough, displayed velocities went higher every round for 5 rounds. So, to hell with it, the unit can't be trusted, and it's headed to the landfill.

I really enjoyed the discussion in this thread, and thanks to all for the comments.
