I think the idea is this:
If you want to meter off a mid-tone, take one or two spot readings off it/them;
If you need a highlight, spot read off the highlight and use the button
(which works well for me);
If you are interested in the various effects that the scene gives, keep
taking spot readings and observe the resulting exposure; compare it with
what your experience tells you should be right and take the photo. I do
this mostly in Auto.
To my way of thinking, the number or readings does not matter after a while
with the third instance.
Please feel free to tell me where I am out to lunch, because I am always
ready to learn...
