[Al Skierkiewicz]

I think perhaps the greatest challenge to teams presenting for Chairman's is comparison with the accomplishments of past teams. The judges are not and should not use past teams presentations when considering yours. Read the criteria carefully and concentrate on getting the most said in the best manner possible. You are working to provide the best presentation of those teams presenting at a regional before you can be considered for the Champs.
From 2009 docs...
The criteria for the 2009 Chairman's Award are essentially identical to those in the past, with special emphasis on recent accomplishments in both the 2008/2009-year and the preceding two years. The judges focus on teams’ activities over a sustained period, as distinguished from just the six-week design-and-build time frame.
The FIRST Robotics Competition is not about machines; it is about the experience of people working together toward a shared goal. Documenting and preserving your team’s FIRST experience becomes an important component of the over-all FIRST experience.

The judges want to hear about the impact your team has made over a period of time. Yes, you can present whatever you think will be meaningful and the judges will listen to everything you present but you also must be memorable. They need to carry that good impression back to the judges room.
