It is only in an ISA atmosphere that the ELR will be 1.98 degrees/1000ft or 6.5 degrees per km (0.65 degrees per 100m). On any given day the ELR varies quite a lot and is very seldom ISA.
The DALR is always fixed at 3 degrees/1000ft or 9.8 degrees per km (0.98 degrees per 100m), and in our latitudes we accept the SALR as being fixed at 1.8 degrees/1000ft or 6 degrees per km (0.6 degrees per 100m).
As it is not the DALR or the SALR it can only be an ELR on a day that is not ISA.

Just for interest sake, as the ELR is 1.2 degrees per 100m, which is more than both the DALR and the SALR you can also see that this airmass is totally unstable.
