First, I have zero interest in game development so that's not an issue for 
me.

OK so the lead knows that they can make things x times faster. Well then 
the demo on the 10-25th percentile machine must not be x times slower than 
what you need on ship day. Exactly the same as would be true if the demo 
were done on a 50th or 75th percentile machine.

As above, this is exactly the same regardless of what the demo is done on.

This is the classic "fast cheap or well done, pick two". For anything that 
will ship, I'll always pick well done.
