I believe this method came from Yuval, but I don't know if it was in the webinar you mentioned. The first step is to run rank performance for the factor to determine which of the middle bars is the best. I used 'higher is better' for CapSp5YCGr% and got the results in the top chart. In the example below, the best bar is bar 11. Use that information to create the formula abs(55 - FRank("CapSp5YCGr%")). Important - always use lower is better for this formula. I also tried using 50 and 60, but 55 gave the best results.
