The flash temperature equations assume a specific pressure-viscosity coefficient (α). For modern synthetic oils, α is much higher than the mineral oils used when 218.01 was written. Without adjusting for this, your scoring factor will be incorrectly pessimistic.

AGMA 218.01, titled “Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth,” was a cornerstone standard published by the American Gear Manufacturers Association (AGMA). Released in the early 1980s (specificically 1982), it provided a comprehensive methodology for rating the pitting resistance and bending strength of spur and helical gears. Agma 218.01 Pdf

The rating formula for (Contact Stress) and Bending Strength were the two pillars of the document. AGMA 218

A: No. Pitting fatigue is covered under AGMA 2001 (now AGMA 2101). 218.01 explicitly excludes pitting and only addresses wear and scoring. Agma 218.01 Pdf

While AGMA 218.01 is often cited in academic research and historical design reviews, it has largely been superseded by newer standards: (PDF) State-of-the-Art Review - ResearchGate
