In that case, the value was just that, a value, the heuristic (ie check) was
indeed a calculation using the provided value.
Methinks that word does not mean what you think it does. :)
(Love that line for "Inconceivable")

Ummm, isn't it just an Empirical Value?
verifiable by observation or experience rather than theory or pure logic

I think you meant "used a heuristing instead of the proveably correct
calculation".
Because applying a heuristic is indeed a calculation.
It may not always be proveably correct, but neither are most programs.[ Reply to This | Parent | # ]

In our case it was a high precision navigation system. (well before GPS)
We knew how the implemented algorithm worked, AND where in the world the
navigation system was going to be used.
To save time we had created a table of fudge factors that operators had to
select an entry from to compensate for the known bias introduced by the
algorithm. The navigation system was x/y based rather than
Latitude/Longitude/Altitude, so the fudge factor was how much to make the x/y
plane intersect the "almost" spherical earth. Close to the x/y origin
meant a small value, over 100-200 miles and the value was a good bit larger..[ Reply to This | Parent | # ]
