The proceedure for backing the weight of fluids out
of the W&B calculation varies by model year (or
serial number range). The proceedure is specified
(By Cessna) in the 182's Type Data Sheet, which
your IA should be looking at during an annual inspection.
I have a copy of the TDS in my logs with all of the relevant
parts high-lighted for my L model.

I didn't realize it was model year specific, but from my
Type Data Sheet the procedure is to drain all the
fuel, which of course wasn't done. Hence the 60lbs discrepancy.
