Boy...typical response.
If you don't like what someone says; then take an example where it's not the best solution and toss in an insult while you're at it.
I never ever say "Incident meters are the ONLY and best way to measure light IN ALL SITUATIONS..."
Nobody has ever heard me say that...because I don't.
It's not that I don't like what you say. However, when you make broad sweeping and questionable general statements like
"Where the camera will make bad assumptions about the exposure, an incident meter will not be fooled, indoors, outdoors, in all conditions"
and
"It's the difference between "oh..that's good enough, I can goose it up in Lightroom" and "ahh...there is the exact exposure for the conditions, all spelled out in numbers""
and
"I agree...if you second guess your meter at every turn and adjust until you get "close enough" and only have to fix some in Lightroom for exposure. I don't want to spend my time grabbing the steering wheel on the passenger side of the vehicle...I'd like to be the only driver of the car."
and
"Well..I realize the distinction, but in the real world, they get fooled.
Just go out side and point your 85mm lens at something and then spin in a circle and watch the meter do it's impression of a ceiling fan.
Now...which is correct? The reading of the green trees? White car? Blue car?...yellow house?
You don't actually know.
So....technically it doesn't get "fooled" but in practice, it amounts to the same thing."
and
"Except that the resulting "adjusted by eye" metering job by the "experienced" photog is just a guess. could be good guess or a poor guess but it's a guess none-the-less.
Only an incident meter spits out a number."
There are several common threads through the entire series of responses.
1. You are the only person who can be correct on metering.
2. Using an incident meter is the only way to ensure - guarantee, actually - precise results. (only an incident meter spits out a number).
3. Reflected light meters are inherently inaccurate, and therefore somehow less suitable than incident metering - because they can be fooled.
4. When challenged you project. I asked several times how best to meter a number of different scenarios with an incident meter. You could not bring yourself to admit that it could not be done.
5. In all likelihood, your bias against reflected meters, whether in camera or in the form of a very precise 1 degree spotmeter, prevents you from embracing a different way of doing things that I am sure is used by most successful landscape photographers (the OP's original question), and a variety of other venues.
I stand by my comment. You can't get your head around the Zone System and how to rely upon your experience and knowledge of your gear to properly and competently evaluate the tonal values to precisely, in EV - assign any tone to any zone in the zone system. I get that. I would suggest (at the risk of sounding insulting, not my intention at all) that you might just want to look into that (or not, your choice), as it would probably enhance your skills and make you a better photographer.
This is one of those rare moments where Floyd and I are in complete agreement on a subject - in camera meters are fine. Incident is best used under controlled lighting, or when the contrast range does not exceed the dynamic range of the camera. Otherwise you risk blown highlights.
My favorite quote on the subject is this:
"Hi Bill. In theory, a spot meter reading off a gray card (angled as recommended by Kodak) should give the same result as an incident meter reading. But a better approach is to use the spot meter to see what the range of the scene is, allowing you to be sure that the highlights won't be blown out. The spot meter gives you more control, but takes a little more thought."

But I maintain that if you understand the entire concept, you can be just as accurate with reflected (spotmeter), in camera spot meter, Expodisc on lens (using the camera as an incident meter), or with an incident meter - except for those times when it is completely impractical to use the incident approach.
My question to you remains, what do YOU do in those situations?
One thing is certain - knowing how to properly evaluate tonality in a scene and how to use reflected light meters - specifically hand-held spot or in camera spot - lets you take accurately exposed images in ANY situation. But you have to invest the time to learn those skills.
I agree with you on one thing - to the uninitiated, it does seem a little bit like guesswork. Just like the cop on speed patrol who can estimate your speed within 1 mpg at 65mph even looking through a rear view mirror. It is a learn-able skill.
