The magnetic stand does not document the vertical offset from the base to the ARP. I measure roughly 82mm. What is it really, and could this be added to the product description? (I realize one has to eyeball the horizontal centering on a mark, but it seems the vertical offset should be repeatable.)
The magnetic stand is not a calibrated stand, it can have up to 1 centimeter of error in height. Its height should be 91mm +- 5mm.
