This doesn't say anything about topping off but it is interesting. I got this in an email.
TIPS ON PUMPING GAS (Good information)

> vapor. Those vapors are being sucked up and back into the underground
> storage tank so you're getting less ! worth for your money.

> One of the most important tips is to fill up when your gas tank
> is HALF FULL. The reason for this is, the more gas you have in your

> than you can imagine. Gasoline storage tanks have an internal floating
> roof. This roof serves as zero clearance between the gas and the
> atmosphere, so it minimizes the evaporation. Unlike service stations,
> here where I work, every truck that we load is temperature compensated
> so that every gallon is actually the exact amount
>
> Another reminder, if there is a gasoline truck pumping into the
> storage tanks when you stop to buy gas, DO NOT fill up--most likely the
> gasoline is being stirred up as the gas is being delivered, and you
> might pick up some of the dirt that normally settles on the bottom.
