SUMMARY
The discussion centers on the nature of asymptotic series in Quantum Electrodynamics (QED) calculations, specifically regarding their convergence and accuracy. It is established that QED results are expressed as an asymptotic series in the fine structure constant, where adding too many terms can lead to divergence. The concept of "18 digits accuracy" is examined, emphasizing that one must cease adding higher-order terms once they exceed the magnitude of previous terms to maintain accuracy. The discussion also raises the question of whether the "reversal point" correlates with the optimal agreement with experimental results.
