Interestingly there seems to be a discrepancy of two seconds between the latitude of Cairo (30°) where the annual shift here is recorded as 174 seconds, and the latitude of San Francisco (37°46') where the annual shift here is recorded as 176 seconds.
We would not expect this to be the same as the precessional shift because the time gap here is 366 days exactly, due to the leap day on 29 Feb 2000.
