The problem may be the drainage 'duct' having a sharp bend

Over in the E60 "stinky A/C" thread, it is said that the real problem isn't the lack of drainage of the evaporator collection pan but a too-sharp "duct" which collects water inside of it.

QUESTION 1:
Does anyone know if an evaporator collection pan even exists?
(I can't find it in the realoem diagrams).

QUESTION 2:
Can anyone confirm the real design problem lies in the "duct" shape?

QUESTION 3:
If it's the duct curvature, which duct do we think is the problem duct?
