Statistical analysis of previous recorded data has nothing to do with the predictive power of a theoretical model and certainly nothing to do with the true shape of the Earth.
This shows your failure to comprehend the information provided to you, or your magical ability to cast magic ignore. It has everything to do with the shape of the Earth. This because the shape, mass, area, density, and volume of the Earth has everything to due with how P-waves, and S-waves behave and travel. All of this completely effects the Dynamo, and the dynamics of the data recorded. It effects the time, speed, and distance, as well as the harmonics. It effects how these waves reflect, converge, diverge, deflect, or refract, and it also show's in both the mathematics and the real world data according to RE.. There is absolutely nothing in the data that shows an FE model to which you seemingly can't even establish Parsec.
Is your argument stating that the Shape of the Earth would have no influence on the data? Well
if that is your argument here, I hate to break it to you, but it has everything to do with it!
All I want you to do parsec is to stop playing little circular games and either admit FE has no data, or provide your data. If you can't provide any data Parsec, you have no room here to be making arguments, circular or otherwise.
