You're shifting the goalposts something crazy. I'd like to point out the original poster talked about refinement in the output of the models, not the models themselves. However, having said that, the heliocentric model is still a refinement (and further refinements, which came later) of the geocentric model. We didn't jump right from geocentrism to Kepler's three laws of planetary motion. The Copernican model still had heavenly spheres as a concept: a concept we don't use today. What you're thinking of as heliocentrism is a refinement of previous heliocentrism which itself was a refinement of geocentrism.
