hehe zippy.. I'm an EE and have had my nights in the barrel too. That sounded like a major FUBAR. I pitydahfool who dicked with the settings.

I got the distinct feeling that they rather don't care what comes out of your machines as long as the numbers are the same or bigger than the box is already billed at. If you actually discover it and call them on it it they quietly correct it. Making millions a day on this kind of thing. Just like most hospitals. Get a bill for your child's birth and look at it. About 50% of the stuff you never used, saw, touched, or required. If you actually call them on this stuff they instantly deduct it. Otherwise....$$$

I built a sophisticated leather measuring machine for a local tannery. It could measure the hides (huge jagged pieces like a steamrollered cow) to about +/-10 square inches. They loved it. They loved it because the industry standard was "up to 5% oversize measurements were allowed". The high accuracy allowed them to diddle the numbers up to 10 square inches less than 5% for EVERY side they measured and billed for. Think of it an instant 5% of pure profit! For the whole tannery for millions of hides a year. Sheesh.
