My educated guess is that the pint that is unable to drain unless you take the whole diff cover off, that remains after draining the majority of oil out of the drain plug, has finally been diluted down after a few changes and the fluid looks much cleaner now.
I plan on doing my first diff change next week, 15k miles on my 2012. I am picking up a livestock syringe from Tractor Supply that I will be able to attach vinyl tubing to, so I may remove as much of the old gear oil out of the diff through the filler hole as possible without removing the whole cover.
I'll let you guys know if I'm successful or not.
