This makes sense I guess. These lunar calculations are based on a theory from 1983 that involves, per a NASA document, “a total of 37862 periodic terms, namely 20560 for the Moon’s longitude, 7684 for the latitude, and 9618 for the distance to Earth.” https://eclipse.gsfc.nasa.gov/SEcat5/ephemeris.html
