Works both ways. Look at Browne and Ellenberger, they got worse and regressed when they went to Edmond.
This is the thing that shows Edmonds talent. Ronda at the time was so much ahead of all the girls that it did not matter what camp she was in. The other girls were just learning MMA or never had real talent for combat sports. During Rondas rain she could have trained in her moms basement and probably won those fights.
