Weeelll...
If you were three feet away from the runway centreline when you set heading, then you're going to be 3 feet out at the other end, plus the 2 miles for the difference in the wind.
If you're approximately AT the airfield, that'll do. You should certainly see the airfield at the other end, if you were destined to do so in the first place.
Remember - you have to keep checking your position against the map and the view outside anyway...
