The recent FRC Blog post got me thinking about how changes to the playoff structure might impact teams competing at events where they are also earning district points (Districts and District Championships). While things like four-team alliances and round-robin tournaments have been done everywhere from Einstein to offseason events, every event where teams have earned district points has had some version of a best of three bracket for playoffs.
So I ended up with the following spreadsheet. It looks at an idealized distribution of district points at a 40-team District. It compares the current playoff structure and three different six-alliance round robin options. (See the README tab for more details.)
A: 3-Team Alliances
B: 4-Team Alliances, every team gets 5 points for a win
C: 4-Team Alliances, only the three teams on the field get points
Ranks 1-13 follow the same general trend under all four structures, but it was interesting to me how widely the distribution for ranks 14-24 varied across the different structures.
