It looks like when you created this graph, you had every intention to make robotics appear to be the best deal.

You need listed an average robotics team of 11k budget with 15 kids in the post, but in the graph you used 35k with 60 students. If a team has 60 kids, I feel like it would cost quite a bit more than 35k including travel expenses. Also, I think most schools with only 75 kids on the football team would have trouble finding 60 kids for the robotics team. My old high school has 90+ kids on the freshman team alone, we also have a JV and a varsity team. We have around 5-10 kids from the school on the robotics team at a time.

Another variable is that the school makes money back from sports team through ticket sales, which they do not from a robotics team.

Taking all the data regarding sports expenses from one school is also a bit of a stretch.
