As you'll see from other threads - the gauges may not be accurate in absolute terms, but they do seem to be consistent in their inaccuracy.... Mine always shows 100% when brimmed, 0% at about 170-180 miles driven and I fill up as Aldermog says, at 250 miles also. Doesn't seem to be much affected by how I drive either, which is interesting. Most of us on here are bikers of old, so we're used to driving to a trip meter rather that solely on a fuel gauge.
