I was a bit unclear. The readings measured was incident reading, the screenshot+range is for informational purposes.
I just started trying to memorise sunny 16 to minimise my metering. Last Friday at 1pm Sydney, Australia time. I metered and it was bang on f16. I have no idea about the actual EV and I don't expect to see sunny day for a while.
I'm a firm believer in sunny 16'; also tried and verified it in Florida, Detroit, Orlando, Cologne and Melbourne!
I’m afraid I just can’t share your faith. It seems self-evident that the intensity of sunlight - even in a cloudless sky - will vary with latitude, season and time of day. Also that the correct exposure for a given light level will depend on the type of subject (distant landscape, group portrait, individual portrait, closeup). Indeed, those are the factors that the more complex exposure calculators included. Sunny-16 is at best a starting point.
I'm at 51° N latitude and I live in the second sunniest city in Canada, averaging 333 days of sun per year.
With slide film, a correct average full sun exposure would be 1/125 F11 for a 100 speed film. If I gave it 1/125 F16 it would be a stop underexposed, and that's easy to discern on slide film. So I have always called the rule "sunny 11".
F16 rule I always thought was based between 10:00 a.m. and 2:00 p.m.. I recall the old Kodak film maybe even the new ones has the instruction sheet in it that shows what exposure settings you should use based on light. Sunny, cloudy bright, shade, etc. And even it had 10am to 2pm. So if you shooting outside those times you going to have less light.
If you shoot during magic hour the F/16 rule is pretty much useless.
I found a picture of the instruction sheet from Kodacolor X, ASA 64. I have no idea how old this must be, but quite a lot. Notice its seem the normal bright sunny is based at f/11 (EV14) at 1/125 which is f/16 at 1/60, the f/16 rule for ASA 64. But notice that the sheet also says this rule applies two hours after sunrise to two hours before sunset.F16 rule I always thought was based between 10:00 a.m. and 2:00 p.m..

just as good as a starting point as a $300 incident light meter. just take a few readings yourself. There is an amazing consistency.

You can get great incident meters for under $20.

Kodacolor-X was manufactured between 1963 and 1974. That overlaps with my pre-teen and much of my teenage years, so the sun must have been brighter then!
The most comprehensive exposure estimator I have seen is that in the Ilford Manual of Photography (mine is the 1966 revision). I will try to attach it here. If you follow it through, you’ll find that Sunny 16 applies only to landscapes in summer sun at latitude 45-55N for about 3 hours either side of mid-day. The extreme conditions (eg latitude 65-75N in December) demonstrate in a trivial way the non-universality of Sunny 16. But even on an everyday level, it’s clear that several f-stops lie between Sunny 16 and an outdoor portrait in the early morning in Spring sunshine in northern USA.

But, to excerpt Alan's reply,
"I found a picture of the instruction sheet from Kodacolor X, ASA 64...the normal bright sunny is based at f/11 (EV14) at 1/125 which is f/16 at 1/60, the f/16 rule for ASA 64."
1/ISO f/16 (Sunny 16 rule) is virtually same as 'ASA 64 at 1/60 f/16', so I do not understand where the 'sun brighter then' comment comes from.
Within the past year I did a series of incident reading on various 'sunny' days at about Latitude 38, and validated that depending upon the day 'Sunny 16 was pretty 'rule of thumb'; IIRC, the range measured about f/11 + 0.5EV to f/15 + 0.5EV
Being a resident of USA, I find it surprising that Sunny 16 only applies at Latitudes NORTH of Portland ORwhich excludes most of the US landmass.
