POI confusion - RTH

[AlanTheBeast]

Why would there be a RTH entry in the POI setup in DJI GO?

I checked this out today because I screwed up with it last week. In bad reflectivity conditions I entered a value there thinking it was for ROI radius or height (dumb - I know - as radius and height are set by moving the drone). That RTH setting came back to haunt me later.

Update - Per a reply on Phantompilots.com it is there as a reminder that RTH should be set correctly.

That's not happiness to me. I'd rather one place for each setting - so having a redundant place to set RTH just seems convenience rather than good design.
