You insulted me on the basis of a dumb argument. According to your definitely fighters especiallt champions from beginning to the end, never learn and become better to reach the peak. Everyone in a profession evolves and with more training and better coaching, experience, training and mentoring, evolves and gets to his or her peak. Anyone who plays the fights from 10 years apart, see same fighter fighting completely differently due to evolution (whether in a good way or bad way). I am professional senior Engineer of 20+ years and mentor juniors and no one knows this better than me. She moved from Brazil just shortly before that fight and had not even joined ATT at the time.
Amanda when she was young and inexperienced, fought completely differently than she did when she was 33 - 34 years of age when she retired. Even in that fight, she dominated Zingano until she simply gassed herself out and had nothing left. Zingano herself on JRE said, she has been dealing with CTE since the Nunes fight. That is a cardio issue she fixed after extensive cardio training over the years. Nunes is carrier is defined by how she cleaned out everyone she fought. Not just a single data point. By the same token, Amanda beat every single person who beat Cat Zingano. If you are going to use MMA math and go A = B = C then Amanda destroyed everyone who beat Zingano. She lost to Megan Anderson, for crying out loud who was beaten by Nunes like a deer caught in headlights. If she had truly been great, she would have won some big fights after the Nunes fight, but she fizzled out and no one cares about her. That is just the truth as much as you will get riled up.
