In that event Fred your engine would run very badly or not at all. I'm not convinced by this stretching theory. If that were to happen, the enlarged teeth would no longer grip the sprocket wheels and the tensioner would run out of adjustment with catastrophic results.
Having done it myself, comparing the length of two belts is actually quite difficult with any degree of accuracy. You'll know that they are not pliable and the new one will tend to have adopted the shape dictated by its packaging. If you followed this subject on the forum last year you'll remember that my belts had covered the maximum mileage recommended by MG Rover and had exceeded the time limit by over three times. I found no evidence of stretching on any of them.
I hope that the rest of the job goes well for you Fred.
