It depends. If you are adding water afterwards, then of course the OG of the boiled wort would be very high and completely inaccurate. You also have to know the exact volume- not 3 gallons left, but 2.65 for example.
If you're doing a full boil with all of the wort, and you know the exact volume left in the kettle, it'll be highly accurate.
