Which factor most limited the accuracy of calculating time or celestial positions using medieval astrolabes?

💡 Explanation

The accuracy of astrolabes was primarily limited by mathematical approximations used in projecting the three-dimensional celestial sphere onto a two-dimensional plane as precise projections proved computationally prohibitive at the time. Therefore, mathematical approximations in projection limited accuracy rather than manufacturing variation or standardization, which represented practical challenges but affected precision less.
