OK, I looked at routegadget and I think get it now.
I think I would have been OK on course C - You have to enter at the top level and wouldn't lose much time trying to find steps down at the south end of the bridge (looks like Brian Ward did) - then knowing there wasn't a connection between levels then 18-19 must be direct.
However, for course A I'm not sure how it would be possible from the map to deduce that the optimum route from 29-30 is round the south then back north between the buildings underneath the bridge. And I don't think I would have have worked it out from the black dots on the RtC map either - even with it coloured grey.
