During 2003 the method of recording the sea level at Rodhos was changed from recording downwards to the more conventional recording upwards. The elevation relevant to benchmark R 4 is now 1.916m giving a revised RLR factor of 6.484m. Data points Feb - Aug 1992 flagged as the data looks anomalous when buddy checked with data for Leros. Although Leros is a way away the sea level profiles are in the main comparable.
