/**
 * Landholder's C is SLIGHTLY decreased proportional to the profit obtained by
 * the winner.
 * 
 * In some situations, land holder has made multiple bids and he is unsuccessful
 * in all of them. Some of they may have won by other land holders, and some of
 * them may have not won by any. It was assumed that, if no one has won, there
 * is no effect to the land holder's Conservation Ethic. So, the unsuccessful
 * bid, which has given the highest profit to the winner is used for the
 * calculation.
