In 86589, Jeff points out mysterious noise seen in SRC2 Y CTRL between 1 and 3 Hz that is only seen when the SR3 estimator is fully on with the L to P contribution included.

To verify this, I plotted some other times with the estimators ON and OFF, and looking at those different times, I was able to confirm that the unknown increase in noise Jeff points out between 1 and 3 Hz is NOT caused by the estimator, but by some other noise source in passing.
