I do that only for a basic circuit that is new to me. A 'real' circuit
often consists of a number of basic circuits, which I recognise and
'read' the same way I read text: not letter by letter, but word by word,
and somtimes even a whole phrase at a time. You've got to learn the
'pattern language'.
