The essence of it is that "PEF" is from the user's point of view - pain, effort (work around), frequency. "REV" is from the developer's point of view- risk, effort (fix), verifiability.
Something that has a low PEF score and high REV score would not be practical to fix while something that is high PEF and low REV is something that should be prioritized high.
