Well, it looks like cylinders ruin everything. From what I can see, there are 2 mechanisms: the eye itself shrinks and grows based on defocus, and then visual perception changes, but it can only adapt to change near a certain focal plane. That's why blur adaptation is bad, as the axial length and visual perception go out of sync, possibly resulting in lots of accommodation to "simulate" myopia when making the light input match visual perception's requirements. Whenever a cylinder is changed or spherical on one side is changed, it distorts everything much worse than spherical changes, and affects later focal planes. When undoing the changes, after you hit the cylinder, it applies the cylinder to the entire focal plane, and then you have to undo it for the entire focal plane before continuing to reduce. Because it'll be "too hard" to adapt to too many changes, that's why it's better to resolve the cylinder at closer focal planes before continuing.
