I think you may have a good point there. A certain Asian airline requires the masks to be tested and re-stowed before every flight by the flight crew. There have been countless occasions where the re-stowing was incorrectly carried out rendering the quick don function to be lost!
So, because of incorrect re-stowing, the solution is to re-stow it every day?
I agree with Denti, let the engineers handle the re-stowing of the oxygen mask. As a pilot, your main duty is to stop the oxygen flow (usually by closing the left door and pressing the test/reset button) when you don't need the mask anymore and verifying it has indeed stopped.
