Quick Sheets

Have you used any of the "Quick Sheets" published by The Genealogical Publishing Company over the years? Several years ago SGS purchased a number of the QuickSheets created to accompany Elizabeth Shown Mills' Evidence Explained book on citing genealogical sources and I bought one of them. It's been a lifesaver for me. She actually generated a series of QuickSheets for citing different kinds of sources.
Now Ms. Mills has a new QuickSheet available: The Historical Biographer's Guide to the Research Process. You can read all the details here. I haven't actually seen a copy, but it sounds like a quick "how-to" guide to the research process, data organization, and evidence analysis. The description on the GPC website ends with "If the objective of research is to reach conclusions and establish proof, this QuickSheet will get you to your goal with absolute confidence." I'm not sure how 4 laminated pages can make this happen, but it's certainly an interesting premise.
What was more surprising to me was to see that GPC and Elizabeth Shown Mills have developed two other QuickSheets related to DOING research (as opposed to CITING research sources):
--The Historical Biographer's Guide to Cluster Research (the FAN Principle)
--The Historical Biographer's Guide to Finding People in Databases & Indexes
These sound like they could be potentially very useful.
Have any of you readers seen/used any of these?
