My "exact" location from Google Earth was:
34.403, -119.694
Using a "rapid-fire-fix" (term coined by Frank Reed) procedure on the four Saturday morning sights I get:
N 35d 34.7' stdev=98.7'
W 119d 20.4' stdev=29.7'
which is separated from the "exact" location by 73 nm.
Using this "rapid-fire-fix" procedure on the nine Sunday morning sights I get:
N 34d 23.9' stdev=23.8'
W 119d 43.4 stdev=61.0'
which is separated from the "exact" location by 1.5 nm,
and by 16.5 nm from the location determined by the noon curve calculation (N 34d 29.1' W 119d 24.5').
I never took a closer look at those "stdev" values like I once had planned, but once again it seems that they tend to overestimate the real error of the result.

I reformatted my recent post into a more readable form and attached the resulting PDF. Peter
