Now that isn't a huge credit list because I have to be bribed or otherwise coerced into shooting movies. The bulk of my career has been television, and the bulk of that is TV commercials, a couple of thousand of them over the last three decades, many for national clients. I'm retired these days, hate and avoid LA, work on my art and my vineyard, and sail my boat. I still shoot a few local spots for folding cash. The point is that trying to impune my street cred is a backfire.
I do occasionally have a meter re-calibrated if it seems to be misbehaving, but specifically on movies or big commercial projects we shoot tests with the specific emulsions and batch we are going to use, using the meters lenses and bodies that will be on set. If the batch number on an emulsion changes, we would test that other batch as well. That's how its done.
Again, a day of testing is worth an infinite number of calibrations.
