Have had mine mic'd on many, many occasions. A friend owns a shop and a termlab meter. of 40 possible points of measurement, My best has been a 37, my 3 missing points being att the extreme low end of the spectrum, 20, 25, and 50Hz.
I currently use TruRTA software to tune my car, and it seems to be pretty dang close to the termlab numbers. All testing is done at 90db.
Points are taken when any octave differs from the next by 2 db or more.
Your curve does not need to be flat, just smooth in its transitions from neighboring octaves.
