Thanks, Rogier

So, the guessed formula is correct: scores = 3*points - c
c = 20 + 144 + 64 + 2*28 = 284
EAST won, so scores = 3 * {20, 144, 64} - 284 = {-224, +148, -92}
EAST score = -(-224 + 148 - 92) = +168

My setup is almost the same as yours, except EAST score is derived from others.
This simplified coding, since EAST had very different rules than others.

Example: what if NORTH was the winner ?
scores = 4 * {20, 144, 64} - {284, 284, 0} = {-204, +292, +256}
EAST score = -(-204 + 292 + 256) = -344

WEST, not a winner, gain most points !
WEST, gain points no matter who win !!
