Why is NDLDRAPU/NLDIAPU axis data cited everywhere as "-420/280" when it actually should be 700/1000? I mean, I can see where it comes from: when you create the map in OLS, it automatically (erroneously?) changes type to "eeprom, subtract". Are there any maps in ME7 that actually use axis data like that?

I x-reffed the lookup function for NDLDRAPU in ME7.1.1 - and it's basically the same function that's used for lookups of FPLMRM, FKFPEDV, etc - all maps with "normal" axes.
Which leads me to believe that this whole deal is an ongoing mistake and should be corrected in known definitions.
