Drive shaft axial end play GQ and GU difference

[42south]

Hi guys
My td42 Y60 has Y61 auto lock free running hub, and wheel bearing lock nut system fitted.
I am confused because the GQ manual states that the end play between the snap ring and the mating parts should be 0.2mm or less. However the GU manual says 0.4mm or less. Since my axle has the GU locking hub and wheel bearing lock nut fitted Im thinking to use 0.4mm as the tolerance.
Im looking for any guidance some one could provide?
