You're right, I'm really, really not
You tried to justify a larger shipped figure in the quarter than can be explained by sales, by claiming that if it were any different, there would be empty shelves at the end of the quarter. I pointed out your logic was incorrect, as feedback from retailers influences future shipments throughout a quarter.
The only time shelves can be bare is between the sale of the last unit of shipment n-1, and the arrival of shipment n. For that to only occur at the end of the quarter as you said, is to imply only one shipment per quarter, at the start of it. Otherwise how do you explain it not happening in, say, mid-November? Why do you assert it only happens at the end of the quarter?
Furthermore, your explanation also falls over when you look at multiple quarters. If you are correct when you say that a larger shipped figure than sales figure in a quarter is to prevent empty shelves, then by implication after two, four, forty quarters, this surplus is going to increase cumulatively. Of course this is ridiculous. In actual fact what happens is, if there are any surplus units from a shipment then the retailer reduces their request for a future shipment to redress the balance. The clearest example of this (large enough to be clearly visible in the quarterly numbers) was Oct-Dec 06 and the following two quarters.
As for your final point. Of course there is a delay between the units being shipped and the units being sold (by definition, the unit has to be shipped before it can be sold, right?). So you are correct, some units might appear as shipped in Oct-Dec, but sold in Jan-Mar. But again, your logic fails, because by the exact same argument, some units might appear as shipped in Jul-Sep but sold in Oct-Dec. You are once again trying to justify an increase by looking at the end of a quarter, without applying your own argument to the start of a quarter where it has the opposite effect.
To be honest, I'm becoming a little tired of being your sounding board for ever more illogical explanations for a larger shipped number than looks plausible. Considering this was your first post in the discussion...
whats over shipped mean , if they have a console left on shelves anywhere taht means its over shipped ?
...I no longer wish to be your personal "shipment tutor", and perhaps this thread can move on?
