In 7 years with the company I have never met a skipper who didnt take what he (or I) were happy with as a fuel load. I've met about 3 who have seen a fuel table (& that was only for curiosities sake.) Our managers may not be geniuses (!) but they are not daft enough to push people to take less fuel than is necessary.
Edited to say MM - we crossed maybe you were one of the curious ones!
