Multi player scoring is tricky when there is a timeout win.
Table 1 should be:
Player2-2 points
Player1,3&4 - 2/3 each
Table 2 should be:
Player1&2 - 1.25 points each
Player3 - .5
In a timed out game everybody receives some points just like in a 2-player game.
Chris Bany has a scoring spread sheet for 3,4and 5 player multi player games giving the correct scoring for every possible outcome. I just have a hard copy. If I find my computer copy I'll post it. Otherwise Bany will send it to you.
