It sounds to me like someone's students need to be turned loose with
a FFT program and LOTS of this gathered experimental data!
I thought "someone's students" already have. See below.

Both our results and NOAA's calculations showed no
correlation of high
water or Spring Tide to anything: Moon or Sun position, Moon or Sun
period, etc etc. for any location (except for amphidromic points)
I quickly downloaded a year's worth of hourly data from that NOAA site
and performed a SFT (slow fourier transform - I wrote it myself) and found
a very significant peak at 12.42 h and smaller ones (but very clear) at
12.00, 12.66 and 23.93 h. It wasn't until I did the SFT that I compared
the results to the list below.
M2......12.42hr..Principal Lunar -- The period used by
the NewZeland
site
S2.......12.00.....Principal Solar..........
N2.......12.66.....Lunar Elliptic...........
K2........11.97....Luni-Solar Semi-Diurnal..
K1........23.93....Luni-Solar Diurnal.......
O1........25.82....Principal Lunar Diurnal -- I assume
= John's Mean
Lunar Day
P1.........24.07....Principal Solar Diurnal..
Was I *not* supposed to get these peaks?
