I've been told that "in truth", an estimate is supposed to be a
/range/, not a point. (Though I have heard the phrase "point
estimate", which is, I suppose, a point.)

I wonder what would happen if we estimated "I can do that in 2.5 to
5 days", rather than "I estimate that as requiring 5 days." I'd be
concerned that "they" would just assume the 2.5 ...
