Which limitation arose when early astronomers estimated planetary positions using epicycles?

💡 Explanation

Early astronomers found the need to correct the epicycle model because the observed *irregularity of retrograde motion varied in speed*, rather than being consistent with purely circular motion. This required continuous model adjustments, because inherent geometric approximation introduced errors and therefore limited long-term accuracy.
