This one happened to my mate just the other day. (Can't remember exact words, he may be able to help out.)
Flying into BK from Prospect, and as usual, he was required to report on final at 3nm.
A/C - "Tower, ABC is 3 miles"
TWR - "ABC, from where I'm sitting, you seem to be about 1 1/2 miles. Maybe one of us should touch up on our mileage technique".
What can u say to that??
Cheers,
