I don't think Mikecr was saying you were a liar but was really asking how you are measuring TIR. If I'm wrong then fight away. I actually was wondering myself from how it was written, are you measuring the total swing of the needle on your gauge for each individual case as you roll it through a full 360 degrees on your V-block and then taking a average of that for multiple cases or are you only checking it at 3 spots per case 120 degrees offset? TIR should be measured through a full 360 rotation for each case.
