I'm also running into similar scoring problems. Game #994 is a good example--in a two-person game with equal numbers of ships on each side, we have both sunk all but one of the other person's ships. The two remaining ships have point values of 24 (my opponent's) and 26 (mine). All things being equal, our total scores should be roughly tied right now, but in fact my opponent has a total score of 74, while I am registering at 36.99. (The decimals from rounding shared kills are a little annoying, too.) Several of the sunk ships haven't registered in the event log, so I'm guessing this is why I've lost a bunch of my points.
