They asked for your track because in it, you're the one flying. What you wrote there is like asking me to go to the doctor instead of you for coughing. I may cough to call a bullshit while you might have asthma. Who knows. Yeah the same issue could have been caused by several different things. Resurfacing the break rotors took care of the squeaks on my car but doesn't mean it will for yours. So for you, the tail wheel doesn't lock even when you pull back the stick to its limit? Well, mine does lock but I still had trouble taking off. Would my tracks have solved your problem?
