Watts, everything is involved. All the the topics we covered so far are a huge part of it. Yes, market price matters, however what Richard said about going from 600k to 100k is a huge determinant. If a manufacturer wants to do R&D that they will trickle down to their other lower lines, then they can make the assumption that at 600k, they'll sell only 3 for the year, but if they go 100k, then they can sell 50 for the year. That would be what you are talking about I assume? The market at 600k will relate to 3 sales and that's what the market allows, but at 100k for the same thing (economy of scale) then you sell 50.
