So, the center of the FRC world is Kalamazoo? Who knew?

I mean, besides 2767?

Re: pic: Average Travel Distance for FRC Teams to US

What about if you limited it just to teams who attended champs last year? Maybe it would make Michigan teams pull things a little less (though on second thought maybe not?)

I added three new sheets that do as you suggested, didn't make much of a notable difference.

Correct, so for all the teams who go to the southern championship, they are traveling an average of 2036 mi (Harris County TX) as opposed to the minimum average distance possible which is somewhere in Colorado (~1900 mi).

Re: pic: Average Travel Distance for FRC Teams to US

Interesting that the South Champs has such a small automatic mileage spread on the color scale. It looks like there is a pretty wide swath of the West and South that can be chosen for South Champs with very minimal travel mileage impact.

I wonder how deep you would have to put south champs to minimize the straight-line distances.

Haha. Me too.
I guess my conceptual issue was I was thinking of distance from counties, with counties being weighed evenly... not by teams that actually exist in those counties. Explains why Alaska didn't pull South Champs into Oregon.

This is probably because of the large international presence at South Champs. A South Champs (USA only) would probably be more relevant).

Re: pic: Average Travel Distance for FRC Teams to US

Yikes, what happened to Oglala Lakota County (Shannon County) in SD? Were county seats used as an endpoint to calculate distance? This is the only explanation I can think of (Oglala Lakota County is the only county in the US (that I know of) to have its county seat outside of the county).

Is it possible to recalculate the distances as Manhattan distance? Then average the Euclidean and Manhattan? I have a feeling that will give a much closer representation of real-world travel distances. (Whether or not it is actually useful is another matter entirely.)

If I had the free time I would dive into this: https://stackoverflow.com/questions/...s-driving-time Select maybe 2 dozen candidate cities vs the team subset and let it go to town (no pun intended). Pick the city with the lowest residuals, boom. (It might hic-up where no road network is present (i.e. Hawaii)).

Also a quick cartographic tip to the OP (not trying to be mean), since you are dealing with difference and not a variance (i.e. positive only values) you should be using a monochromatic color scheme. The current color you are using is really only commonly applicable to +/- situations, such as standard deviation. The point I am trying to make is the eye is drawn to the ring of low saturation hues, and not to the point of your map: the geographic center of a distribution.
While the map is easy enough to read, the color scheme adds complexity where there doesn't need to be any.

It would be interesting to optimize on multiple sites (an arbitrary number from n=2-100) minimizing distance from the closest site for all the teams.

And also interesting to redo that calculating driving distances (e.g. Google Maps API).

You could also add a constraint about how many teams can go to the site, so you wouldn't have a bunch be at a single site.

I may or may not have decided I need to play with this right now...

All they need is a big building, a bunch of motels, and a big parking lot, but it's the fairest.

From a realistic standpoint of actual travel distance, proximity to a major international airport is key, ESPECIALLY for south champs. By major, I mean one where international flights come in from many directions.
