From the transcript
Rather than trying to decipher all these colors, what we did was we created a plot that just shows the age 50 values, or age at 50%, percent maturity and what the, what those shifts look like through that time series. As you can see, there's two distinct lines there. The one on the top is what the visual estimate is giving that's not calibrated by the histology. And then the solid black line is the calibrated visual estimates through time. And as you can see here, from 2002 to 2016, there was a, decrease over— or an increase over time to older maturing females and an increase in the age 50 and then a sharp decrease down to 2021.
