Re: 2014 Curie Division

Re: 2014 Curie Division
I think that seeing a team's elimination record at a glance tells you meaningful information. A team with a 12-0 elimination record certainly looks different than one with an 0-2 eliminations record.

Re: CPU spike to 100% - robot unresponsive
I have helped teams debug this problem at events many times over the years, and the majority of the time the issue is a "for" or "while" loop where there shouldn't be one. With an Iterative or...

Re: Teams Missing from this Year's Championship
168, assuming nobody declines the invitation.
