Why not make it simple?

Profile|1.0|A|B|C = 0.0 +/- 0.5 right?

I take my highest plus material point, (+0.6 in this case)

And my lowest minus material point (we'll pick -0.3 since it was not mentioned)

And write:
S/B: Profile|1.0|A|B|C
IS: Profile|+0.6/-0.3|A|B|C
OOT: +0.6

We’ve told the people that need the data what the actual high and low is with little room for error.

If you have a unilateral tolerance zone, it’s the same “IS”, but the S/B needs more descriptive info. Let’s say the entire zone is at and outside the nominal.

S/B Profile|1.0|A|B|C, Outer Disp. = 1.0 or
S/B Profile|+1.0/-0.0|A|B|C
IS: Profile|+0.6/-0.3|A|B|C
OOT: -0.3

Hmmmm, that leaves the case where all my points are on one side of the nominal. How does one report that? Really it’s pretty simple. Well use a case where we have a bilateral of 1.0 again. But this time our highest point is +0.6 plus material and our lowest point is +0.4 plus material. So our range is only 0.2.

So we write:

S/B: Profile|1.0|A|B|C
IS: Profile|+0.6/+0.4|A|B|C
OOT: +0.6

I like always reporting the S/B with the zone dispo visible. Like:

S/B Profile|+0.5/-0.5|A|B|C

It lets anyone reading the report know the design zone dispo without having to refer to the drawing.

In each case above we have communicated the range of actuals and the disposition of that range about the nominal. I think this makes it a clear. (as mud? :-)

Of course any method you use, assumes that the people that read the report can understand it. As Murphy once said, "If one can read it wrong, they will". Something along those lines.

Good luck!
