Has she changed coaches? My wife jumped 19-1 in college. After college, we decided to keep training for fun with me coaching us. She improved every year for the next four years, ending with a 21-4 as her PR.
In her case, I had a completely different approach to building speed and strength than her (our) college coach did and made a huge difference for her. In a lot of ways we trained less intensely, but it was very different than her college training.
I dont know Franklin's story, but it wouldnt surprise me if it was different coaching.
