What does each bar on the fuel gauge represent? Miles or fractions of gas?

Just thinking out loud here; I wonder how tolerant the sensor is to gas slopping. Fairly small tank so bumpy roads should get the fuel sloshing about pretty good making a float based sensor have fits unless there is some averaging circuit to compensate for a dirty signal (i.e. a lot of ups and downs) from the sensor.

I know if I put the bike on the side stand there are times she'll get a bar back so its' affected in that state. Perhaps I'm over thinking this.
