The overall trend is that it is overwhelmingly more likely that a front bell will be rung by a woman than a back bell will be.
Where there is discussion about the lack of female conductors, it is often speculated that a lot of conductors call peals and quarter peals from around the middle or back section of the circle, often from a traditionally “fixed” bell.
This chart compares the probabilities of specific bells and positions being rung by women (in green), and also by conductors (pink) for quarter peals in tower.
