Is there any particular reason why GNSS-derived Altitude (GA) in subfield 4 of I062/110 is not scaled? As per notes in the spec:

GA is coded as a 14-bit two’s complement binary number with an LSB of 25 ft. irrespective of the setting of RES.
The minimum value of GA that can be reported is -1000 ft.

Suggest adding scale, minimum and unit to GA. Proposed changes and a sample message capture are attached.
