I would say it shouldn't have an effect... The tables are computed and built
as relative during profile creation; after that, the wp should only be used
to bring them back to absolute when abscol rendering is requested. If relcol
is requested, they should be used as-is.
Isn't that the idea?
However, it hasn't proved true for me in the past either... More than once
I've seen the wp tag influence the relcol rendering.
Different for each CMM, of course :(
I always hope someone will step up to explain such a thing...
More on next post.
