J,
You don't believe anything? I think you hold a very strong believe.
I haven't dismissed spot meters.
Nor do i think that precision does not matter.
(You probably think that, because i'm not joining in in the "a spot meter is best, the tool of the select few who really know their stuff" choir, while you appear to be singing the lead.

)
What i am saying is that with any (!) meter, you can get the same excellent results, because that does not depend on the meter used, but on who is using it.
And it is not difficult; you do not need to be a genius to know how to use one.
But when you are not, the spot meter is the least likely to help you get excellent results.
Quite simply because it, of any type meter, puts the highest demand on your skills of interpretation. (You call it precision, and say that it is something the meter offers. I say that to turn what the meter tells you into 'precision', you have to work at it yourself).
And here's a test you can run yourself: next time you start are using your spot meter, also carry an incident light meter. After carefully assessing the scene with the spot meter, and having decided upon an exposure, meter the scene using the incident meter. It will tell you the same 'in one go' your spot meter eventually told you.
What the incident meter does not do is tell you the brightness range of a scene. It will not tell you whether it needs compressing or expanding.
But (and i mentioned that too before), it's not hard to tell that even without a meter. And yes, that is not very precise. You can perhaps only guess full N-steps that way. But that's precise enough. (It's exactly like how meters like to display f-stops and shutter speeds in 1/10 increments. I have yet to see the shutter or lens that let's you set those thingies with that 'precision', and lo and behold, nothing bad ever came of it).
But the really important bit (and that's why i point to it again) is that you - not the meter - are in charge. You have to assess the scene. Your judgment is asked for. Allways. No matter what type of meter. And that, not the type of meter you are using, is all deciding.
Using a spot meter, you look at the scene, and select bits of it to meter. You then have to judge the result, relate it to other measurements taking from other points you have selected.
That same judging of the scene is done when using any other meter. (It's a process that runs in your head, not in the meter.) And the same decisions regarding how to interpret the readings are necessary. The difference is that when using non-spot meters the process is less lengthy (and thus also that there is less opportunity to get things wrong). The skill involved, the 'precision', and the results are the same.
Oh and: no, i am not dismissing spot meters. I just don't overvalue them either.
