What's the best way to do programming contest problem analysis for groups? (See http://petr-mitrichev.blogspot.com/2015/04/a-week-with-different-analysis.html for details)

This week contained two TopCoder rounds. The first one was TopCoder SRM 655 on Thursday (problems, results, top 5 on the left). Gennady 'tourist' showed really outstanding performance getting the highest score on all 3 problems, and the highest gain on challenges (+350) to boot - awesome job!
