If I remember correctly the pre-production Volt number was .235 which, at the time, was best ever.
After we started production we did a spot check and the number was not what we expected, like .24+, which was a problem because we would have to round up to .25 for the advertising, which we didn't want to do.
After much investigation we found the production cars were building 5mm higher than design intent.
We dropped them back down 5mm and got back to our desired .235 number.
