I agree, and was thinking about this very issue yesterday.  Good
timing!  Fixed.  (I also made additive styles use the absolute
value+negative sign thing, as they're used to generate some complex
numeric styles.)

The CSS specs use the proper definitions of "positive" and "negative"
(excluding zero) throughout, so I've stuck with that generally.
However, I have adjusted a few uses of "positive" to "strictly
positive" where I think it helps clarity.

Whatever is easiest for you.  Multiple small emails are fine for me,
as it's faster to address them, but a single large email is also fine
for me.  It makes no difference to me.
