About scoring methods:
(In what follows, assume that the only passes are the two final ones.)
Area scoring counts empty surrounded + own stones not captured. Territory scoring counts empty surrounded - own stones captured.
Obviously, the difference between these methods equals the difference in number of stones played. That's why, in non-handicap games, the two methods give equal results when white moved last, and 1 more for area when black moved last.
On odd-sized boards, with no sekis, the area score is necessarily odd. E.g. black wins 43-38, or by 5pts, on 9x9. With a komi of 5.5, white would win by 0.5. With territory scoring, white wins by either 0.5 or 1.5. With a komi of 3.5, the winner is black under either method. That's why, with komi 0.5 more than an odd number, it takes a seki to have a different winner under the two scoring methods.
