Grazie

comment wrong, in fact converted ft -> m

Sorry, location was wrong, but elevation has a massive gap between Wikipedia and SRTM/OSM information

Yes. SRTM and Wikipedia indicates that Dún Bhaloir is the hightes point, at around 88 meters.
So I suppose the 200+ values for peaks in OSM are meant - without notice - to be in feet (which is not OSM standard unit ...)
