Did you build & test this? The literature I saw on this type of
attenuator claimed that slide (or toggle) switches didn't have enough
isolation between sections for an accurate 32 dB attenuator stage. That
was why Kay used multiple 20 dB stages.

They probably used pi, rather than tee, stages for some good reason.
