Jaci's Houston Stats & Analysis

With the Houston Championships well within our sights, I thought it’s a good time to take a look at what each division is made of, and how they stack up to each other.

While I am doing one of these for Houston, there’s no guarantee I can do one for St Louis, as I fly back into Perth Airport the same day St Louis Champs starts.

Preface
Carver is going to be a very, very interesting division this year. With the most event attendees, most awards AND highest average OPR, it’s looking like Carver will be the Newton of yester-year. Will we see another upset? Will we see 500+ scores without fouls?

Galileo seems to be the lowest ranked division this year, and seems to be suffering in the awards category. Will Galileo give the other divisions a run for their money on the Einstein Field?

Divisions - Events
Carver takes the cake for most events attended, with an 11 event lead over Newton and Roebling. The other 3 divisions seem to be trailing behind only slightly.

Divisions - Awards
Note: Award winner counts have been adjusted with the above events attendance to ensure a fair comparison.

Carver demonstrating their power with the most wins, finalists and chairmans award wins. Roebling also seems to be going strong in the chairmans department.

Turing and Galileo both coming in with a large amount of Wildcard teams. Turing is the most gracious professional of the divisions.

Newton appears to be the ‘oh so close’ division, with the most amount of finalists in a single division.

Divisions - OPRs
For the uninitiated, these are box plots. The part where the two shades of lavender meet is the median of the OPRs of all teams in the division. The average of each division has been plotted as a solid line, and the average of all divisions as a dotted line. The ‘whiskers’ of the box plot show where the maximum and minimum OPR of each division. Outliers have not been defined, all data is treated as valid.

Although Hopper and Roebling have the lowest OPRs, they have a huge range of OPRs. Meanwhile, Turing, although with a lower maximum OPR, is very tight in its distribution, which should lend itself to being more competitive.

Something to note, is that while Galileo has a much lower minimum OPR and maximum OPR than Turing, its Inter-Quartile Range (where 50% of the OPRs sit) is about the same as Turing (+/- 15 of the median), meaning it should also be quite competitive.

While we’ll see more high level play Carver and Newton, we likely won’t see many close games until playoffs.

Divisions - Score Breakdowns
Please note: Pressure and kPa bonuses are very low since this includes both quals and elims (in quals, bonuses are given in RP, not match points).
See the second graph for playoffs only.

Each division seems roughly equal in terms of Foul Points. Auto and Teleop fuel low might as well be non-existent.

Takeoff Points take a considerable chunk of the total score, as does Auto and Teleop Rotor points. Auto Mobility is consistent across the board.

Interestingly enough, all divisions seem equal in Teleop Fuel High. Hopper and Carver have the highest average Auto Fuel High, whereas Newton and Carver have the highest 4-rotor bonus rates.

Carver and Turing both seem to have the highest adjustment points (red cards), while no team in Newton nor Roebling has ever been awarded a red card. See the below image for details

Conclusion
That concludes my stats dump for today. Feel free to discuss in the thread below.

Have a good time, and see you at the competition!

Awesome charts - posts like this are why you’re in the running for my coveted “favorite Chief Delphi non-novelty account poster of the year” award.

So you’re saying there exists a novelty account that beats out Jaci? Which one?

An honor higher than winning 1/2 champs

I’ve added my Tableau Workbooks to GitHub. You can view these graphs, or make your own, or add your own filters or data by using Tableau. Your mentors will have a code in their firstinspires login for the full version of Tableau.

You will need the SQLite OBDC driver for this, and unfortunately it will only work on windows since Tableau doesn’t support OBDC on Mac.

You can download the workbooks here, with the rest of the database in the root of the repository.

Jaci, thanks for the incredible stats breakdown!

This data’s awesome! Thanks.

Tableau apparently also gives out free licenses if you’re a student anywhere and just upload a photo of your id.

Send her a golden corndog

As always, and once again this is amazing analysis. Thanks for putting out such useful stats!
