So far nobody cared for the difference between "ordinary shipped", "demo stations", "consoles for replacements/spare parts" and "returned (to garbage) conoles". Only now, when we have this whole PS2 debacle, people start to differentiate. My 5 cents on it: I don't think any console manufacturer ever made a seperate list for all the before mentioned categories and counted them separately. All these categories are ultimately shipped/sold units. It doesn't matter if some of them were never used to play or had no full functionality. It was always like that. The only units that don't count are units already broken/damaged/destroyed on the production lane and of course (officially) sold refurbrished consoles. Otherwise, VGChartz has to reduce a certain percentage of all officially shipped consoles by end of production. By logic, this percentage had to be much lower for unsuccessful consoles than for successful consoles and higher for handhelds/hybrids than for home consoles.
It is similar to the infamous "Red Ring of Death" of Xbox 360. If we like it or not, "thanks" to it the total sales of Xbox 360 are higher than they should be.
