Hi.
I never had an issue yet, with GPS not being "on the spot" (the error). So if you let your aircraft set home on it's own, it will set it using the GPS of the aircraft BEFORE takeoff, the DJI app will tell you - then you get the "H" and when you press RTH on the remote or on the app, that is where the drone will go UNLESS he is within 20 METER radius, then he just autolands. Also - keep in min if he is BEYOND 20m radius, he will first climb to RTH altitude - not good if u r under a tree or power lines, if your RTH is too low to pass over something between you and the aircraft. Also REMEMBER - pressing RTH on the remote again will cancel the RTH function, so if for any reason you suspect issues, cancel it, bring it home manually. Most of the controls also work in RTH mode, so u can adjust the landing spot, the path taken to the Home spot... practice in an empty field where you do not have to worry, and can easily get further than 20 meters away. I have never has it land more than 3 ft away from takeoff point, but then again, I always make sure gps is green and the home pos. is autorecorded properly.
I did play once with setting the home from my GPS tablet (using the person icon, note this is not the position of the "radio" as radio does not have GPS, but the position of the tablet/phone, assuming it has good and accurate position set), worked perfect, but I made damned sure, on the map, that it is where I think it should be, and was VERY ready to cancel RTH at any signs of trouble.
If you update the home point while flying, if you use the aircraft - it will set a new home at the current position of the aircraft, wherever it is (no altitude in the mix, just gps map coordinates). A user without special requirement to do this, usually would never need to do this. Majority of us, leave the H where the take off point was.
I certainly do not fault you for reading the manual and being careful, not enough people do this, but also, is this your first quad, or you are pretty familiar with the controls? Having muscle memory of the controls is quite important - cuts your reaction in case of issue, but bypassing the conscious part of the brain - that is actually a good thing ;)
Oh, one more thing for GPS, I never have accuracy issues, in the US, not sure where you are... it is possible that esp. when not using the US side of GPS sattelites the rules on the GPS may be different, not sure.
Anyhow, do not be overly afraid, fly in P mode, no high winds, no crazy speed, big open field, and give it a cautious try.
Certainly go through the various tutorials, like say this set:

Also, use the simulator.. cannot go wrong with using the sim, EVER!
Good luck and keep us posted of progress!
