Hi Dan, How's retirement going? Have you figured out the time distortion, as in, how did you get anything done when you were working, 'cause you don't have enough time now to get anything done? Ha ha, it's good to hear from you, my friend.
That's a good question and relates to how Bob and Fitz'es findings sort of merge. I remember the article and I believe Bob's "Things That always work," came out after Dave's study on stabs and elevators was published. That would be after 2000, and before 2010. I wish I could be more exact.
If you locate the article, and wouldn't mind, I would be happy to pin it alongside Whitely's article. A lot of problem solutions seem to fall under these two pieces of work.
Keep posting Dan, you're helping a lot of people as they venture along the CL PA path.
