Bloggs, to minimise the glare of the blindingly obvious, consider ‘longer’ as being of the same runway length, but the conditions at the time of landing make it limiting.
The conditions which determine ‘limiting’ are either those where the crew have direct control – flap, brakes, speed; and others requiring judgement based on reported conditions – and flying accuracy.
A proactive uplink based on previous landings could simplify some of the choices, add confidence to a decision, and improve knowledge of the safety margin.

‘There is no truth’ (bio); only probability, risk assessment, and choice, all of which have to be managed.
If we believe that we are able to consistently judge when to aim for, and achieve an accurate landing, then perhaps we should reassess the probability of our behaviour (and it’s not error free).

FDM can provide an insight of our management process; a gatekeeper / interview for each transgression might help us review what happened, but less so the reasons why.
The alternative of looking at all landings (no gatekeeper required) could provide a probability plot of individual or operator performance and the likely-hood of achieving a particular standard, a standard required for a particular situation – a limiting runway. How certain can we be that a runway is limiting or not ... ... there is no truth?
Many would say that this is airmanship, experience; but it would be an advantage to have a measure of past performance, to use real data and not have to rely on memories based on individual belief.
