No plan survives contact with the enemy, everyone has a plan till they get punched in the face, etc. While it's true that Claudia could've made things a lot easier for herself by doing what you've said, I don't think she has the cardio and skills to keep it up for long enough. Even Joanna couldn't keep Andrade stuck on the outside for a full round, and she had to use her clinch game to bail her out of trouble & reset. Sooner or later, Andrade would be able to force a clinch/grappling exchange with Claudia and from there it's all downhill for her. I thought it was pretty close odds on whether Claudia could keep up her distance game long enough to win 2 rounds, but I was mistaken. She got put off her game a lot earlier than I expected and Jessica just ran away with the fight.
