PJ2, I sense from your question, and from several replies, that the focus of the discussion is on transgressions, identifying the deviant occurrences, and thence drifting towards blame albeit under the cover of seeking to understand an event.
This is typical of chasing the symptoms approach to safety vice looking for the underlying disease. Identifying a few spotty faces based on the degree of redness (crossing the limit) is not an indicator of operational health; after all who sets the limit, why, what does a transgression actually mean, …
FDM has the ability to provide an overall health check, but this requires looking at the wider picture, looking at the widest spectrum of data possible, what is normal, patterns, and thinking about safety.
Europe has made inroads to this type of FDM, see:-
European Operators FDM forum, where a partnership between operator and regulator has a common objective. Look under publications and conferences for example materials, e.g.
FDM and Safety Promotion
Deep and Long Landings and of the Runway Excursion Risk.
