I think that if a player drops out, it means that their games, including those they played, should be either considered invalid or valid under the condition that all the other players who didn't play against them also give technical wins to that player.
If a player has played half or more of the games, they receive technical wins in the unplayed matches, which affect the distribution of places. The rating is calculated.
The most important thing to understand is: rating and the distribution of places are different things and exist separately.
I have corrected the table.
