Ah. So your argument of voter preference for this system is entirely specious. Thank you, that tells me all I need to know.

It's not bugs in your software, it's the assumptions made when writing the software and creating the data. Social utility/cost benefit/"economic man" arguments are always liable to drift away from reality, unless cross-checked against real-life preferences. (See the staggeringly inane "Everyday Economist" columns on Slate magazine for an example.)
