No, that's not correct.  You *can* assume things about the range (i.e.,
the ranges are meaningful), but just not everything that's currently

But given the proximity of the GCC summit and since many of the people
who are most familiar with this issue will be there, it may be best to
hold off on this part of the discussion until it can be done in person.
