It's not us - if you're referring to ATC. It's the airport authority! The same system they use to determine how many of you guys are flying CDAs they use to bollock us for turning you on at 9.999 miles from touchdown when it should be 10 miles from touchdown during the night hours. We don't mind if you make the CDA or not but the loonies who live for noise abatement take it all far, far too seriously and get terribly excited if you don't!
