More data equals more information but more data also equals a longer test duration. The minimum data requirements for full factorial are very high since you are showing every experiment.

I have been studying DOE techniques (実験計画法) for social sciences at Kyoto Univ in Japan since 2007. One thing that is important to point out is the ability to measure main effects is equal for both full and fractional tests. Along with the "camps" that you mention, we are using a product called SiteSpect for the study of controlled experiments using both fraction and full factorials. This has helped us with optimization in online media in Japan. They have large repository of documentation that can be accessed from their website www.sitespect.com. thank you! ありがとうございました Shinchi Greetings,
