Bounty: 400 SPR

For shits and giggles, if someone good at math would like to do an analysis to find the most efficient determination of how many Darkcoin would have to be sold and how many Spreadcoin would have to be bought (with the total BTC that would have to be spent for them) for SPR to pass Darkcoin in price, in a manner that at least makes sense as I understand there are many variables, I'll pay you 400 SPR.

For example, if there is a 1000 DRK buy wall then selling into that isn't going to be efficient.  So 0 DRK would need to be sold but XXX,XXX SPR would have to be bought.

Or the most efficient means to do it would be to sell 23,450 DRK and buy 114,500 SPR because of current and anticipated buy and sell walls.

Not easy math I understand.  It's far beyond my capabilities.
