@mightymoe Which is why I like surveying on the coast...differences of elevation of maybe 100' with distances between two points about 300'
@rover83 finally someone gets it. Lol. Look you need to line up and join up for geodesist position. We need folks with your ability in that group. ?ÿAsk not what your country can do for you but what you can do for your country. ?ÿYou probably have the skills and talent needed to join up.
Suppose the earth is a sphere radius of 3959 miles at sea level. Surveyors A and B both calculate its circumference, but surveyor B, an uplander, uses a radius that is 1,000 feet longer than the actual 3959 miles.
What is surveyor B's precision?
B gets a circumference that is 6283.2 ft longer than A does, which is 1 part in 20,900 or 48 ppm longer than A.
I'm not sure how you are defining precision here.?ÿ If that's 3959.0000... then B can calculate to any precision he wants, but his accuracy is limited (if A is taken as correct). If that's 3959 +/- 0.5 mile, then the precision is 1 part in 7918 or 126 ppm.

What is surveyor B's precision?
surveyor B, an uplander,
Well, it depends...
a) B is not a "flatlander", so there's a strike.
b) B might still be a "troll", but not a "flatlander", so there's another strike.
c) B might be a "Yooper", so B's precision depends on the ratio of: how many Busch Light/Old Milwaukee B has had, how hard B laughs every time he says "pp-em", and what is the wind chill with respect to the depth of snow in the last 24 hours.
Answer: c
