You do wonder sometimes if the landing performance criteria for landing on wet runways is really up to it if "average" pilots are taking it off the end.
I don't suppose somewhere like Georgetown would be up to providing up to date braking action reports for the runway, especially when wet.
On a slightly different tack, many years ago in the USA they put experienced pilots in the simulator ostensibly for some other reason but then gave them a major failure close to v1 on a field length limited runway. Something like 75 % went off piste at the end which led to the conclusion that maybe the take off performance criteria needed re-assessing (not sure whether they did).
Maybe the same applies to landing on slick runways. Personally I never relax till the machine is stopped.
