Average of Defense Crossings- Week 0.5-1

[evanperryg]

I noticed that, although TBA provides some valuable statistics about defense crossings from event to event, it doesn't really show anything about defense crossing overall. I'll work on some visualization, but I made an overall average of defense crossings, including weeks 0.5 and 1:


I was particularly surprised by the drawbridge. Can anyone who's been to competition provide some clarity as to why drawbridge crosses are so rare? Also, if anyone wants any specific style of data visualization, I'd be happy to provide!

EDIT: I will be doing a line graph of week-to-week changes in crossing rates. However, with only 2 weeks of events, the graph is hardly that interesting.
