Great summary and starting point, thanks for this!
I just ran through the whole thing with the Bambulab PLA Basic that came with the printer and turn out I end up at the values the profile had anyway 
The exception is pressure advance, the value still matches at 0.02 but it is turned off in the Bambulab profile. From the test results I would assume I should turn it on but I wonder why this is not the case as a default then.
