Dear all, I am testing the Mavic 3M and obtained an average GSD of 0.79 cm… According to the RMS processing error, when measuring the height of a plant, can I say that I would be making an error of approximately 0.5 cm?

Guys, I’m testing the Mavic 3M and I got an average GSD of 0.79 cm… According to the RMS processing error, when measuring the height of a plant, can I say that I would be making an error of approximately 0.5 cm?  
Or in another way, I must use the rule of 2 to 3 times the GSD of 0.79 cm, that is, the error in measuring the height of the plant would be 2.37 cm and not 0.5 cm. Which is right?
