I would guarantee every airline has a "problem" with stabilized approach numbers. Those numbers are in constant fluctuation. Also, keep in the mind margins that they probably look at. i.e. crossing the threshold at 50 feet, vs 55 feet, vs 100 feet vs 20 feet.
It's a constant battle with the data. Which is why they always emphasize it, and they'll never stop emphasizing it.
You have to look at it from a trend perspective, or even airline vs airline perspective for comparison. Just saying "our stabilized approach numbers" w/o anything reference to anything else leaves a lot to be desired.
edit: like when we had all those tail strikes and they said we were now something like x100 more likely than any other airlines to have tail strikes. That's like a real point of comparison.
