Runout vs. Flatness and Dial test indicators

If I recall (been a while since I've seen this thread and I *THINK* I
started it)...

runout would be measured against the outside rim of the platter, thus
checking for a platter that is mounted off-center.

flatness would be measured against the outer top surface of the platter,
thus checking for a platter that is mounted "at an angle".
