    Are aspheric lenses relatively new on the mass consumer
    market? Expertise on fitting such lenses seem to be
    less than that of spherical lenses.

    Yes, my googling showed questions dating about 10 years back. Then
    again, that's
    when the internet exploded, so it may not necessarily reflect the advent of
    aspherics on the mass market. Thanks for confirming this time frame. I
    imagine that a decade is enough time for experience to develop in
    fitting them.
    I guess they are just sensitive to position.
