OK, I see your point.  Useful advice, thanks.

You still have to account for subject reflectance for some
situations. For example, an incident reading taken on a brightly lit
snowfield (or a beach) will end up giving you overexposure,
because it
reflect more light than a "normal" subject, so you need to stop
down a bit
more. Conversely, an incident reading taken on a black lava field
on the Big
Island will give you underexposure, because it reflects less than
a "normal"
subject, so you have to open up a bit. But as you say, for most
subjects the
incident meter does the job.
