It will only be off a few thousands, but we're measuring in the hundredths, so it is fairly significant.
If you take a reading at 80*F and get 1.050.... the adjusted value is 1.052.
It's only 2 thousandths... but out of 50 thousandths. That a 4% error, which is worth adjusting for. That error will propagate and make it harder to find system issues later if you're trying to nail down volumes or BeerSmith inputs, for example.
