measuring ERD?joe friday

i'm measuring the ERD for a pair of Cadence rims and
according to my measurement, including everything from
the bottom of the nipple seat to bottom of nipple seat, i get 601mm
the published diameter is 609 and i'm wondering if i
need to add an additional length for the various spoke
calculators
as always, many many thanks!!

with a nipple on one end, add 1.5 mm for the other nipple, and round to the nearest mm. It does not always agree with the spocalc database, but always builds well.

I don't have a Cadence rim to compare.
