Which risk increased during the medieval adoption of epicyclic models?

💡 Explanation

Introducing multiple nested epicycles increases round-off error using iterative methods, because these errors compounded during calculation of planetary positions due to error propagation, therefore requiring improved mathematical calculation rather than easing practical instruments.
