They had the 'expected parity with AP1' prominently displayed in the configurator as part of the explanation on EAP up untill halfway January. If you are very patient you may be able to find out with the wayback machine. Otherwise there are numerous screenshots floating on the internet like this one

Do you now at least agree that they explicitly said they expected parity by end of December and not 'first software release'? And if so, how do you re-adjust your last statement given these (new to you) facts?
To recap expected timeline for AP1 parity. Your expectation : half way through 2017 (300 million miles based). Tesla expectation : end of December (based on ?). Why is your estimate slowly turning out better and better while Tesla's is turning out worse and worse?
