I love sitting in the back of the class room with discussions like this.
I'm beginning to confirm things I thought I was seeing correctly, but wasn't sure.
I hope to be more observant of my RMS error [px], I know my RA Osc is very low, Often 0.0X, and never higher than 0.1X.
I don't recall my total RMS error, off hand.
OK, I'll shut up and listen more....
