That's correct, so the threads sloppy or not don't have a bearing on the ER's concentricity.
Andy - is it a home made item or bought, if it is bought it may well be too hard to turn, and it may need to be ground. You still need to check if it is registering correctly.
Where you had your gauge in the video (on the taper) is fine.
