- the number of points awarded for defeating a player with fewer ship decks = (n1+n2)/2,
where n1 is the number of ship decks of player 1
n2 is the number of ship decks of player 2
(4+3)/2=3.5
(4+1)/2=2.5
I suggest:
formula for victories over players with fewer decks: 1+0.25*(n1-n2)
where n1 is the number of decks of the ship with more decks
n2 is the number of decks of the ship with fewer decks
4-deck ship defeated 3-deck ship = 1+0.25*(4-3)=1.25
4-deck ship defeated 2-deck ship = 1+0.25*(4-2)=1.5
4-deck ship defeated 1-deck ship = 1+0.25*(4-1)=1.75
3-deck ship defeated 2-deck ship = 1+0.25*(3-2)=1.25
3-deck ship defeated 1-deck ship = 1+0.25*(3-1)=1.5
2-deck ship defeated 1-deck ship = 1+0.25*(2-1)=1.25
4-deck vs. 4-deck, 3-deck vs. 3-deck, 2-deck vs. 2-deck, 1-deck vs. 1-deck victory = 1
formula for victories over players with more decks: 1-0.25*(n1-n2)
1-deck ship defeated 2-deck ship = 1-0.25*(2-1)=0.75
1-deck ship defeated 3-deck ship = 1-0.25*(3-1)=0.5
1-deck ship defeated 4-deck ship = 1-0.25*(4-1)=0.25
2-deck ship defeated 3-deck ship = 1-0.25*(3-2)=0.75
2-deck ship defeated 4-deck ship = 1-0.25*(4-2)=0.5
3-deck ship defeated 4-deck ship = 1-0.25*(4-3)=0.75
