Bad fuel gauges?

You have not, however, explained why, since fuel gauge accuracy is

Yes I've repeatedly explained that. What I keep pointing out is that
the gauges are typically at least accurate enough to alert you to a
large leak, which is a warning that your flow calculations cannot give
you. That makes the gauges useful (and operable), in a limited but
important way, and explains why they're required for airworthiness.

But as I have acknowledged, the flow calculations are typically much
more reliable than the gauges under NORMAL circumstances. That's fine--
the guages are just one part of how you're supposed to keep track of
your fuel.
