Default Shaft runnout question.

I set up a dial indicator on my lower unit running as far out as possible before the splines. If rotate the shaft 360* the indicator shows a .010" swing. Would the runnout be .005" since a 360* turn is showing when the .005" "bend" is moving closer to the indicator and then when its moving away?

Total indicated run-out is .010".

The .005" that you calculated is axis eccentricity. Basically how far out of concentric.
