Base figure: two hours plus 0.6 h for each millimetre, scaled for each wall. Gatehouse Slab is low-angle and in the sun most of the day. Cold Corner faces north and seeps for three days or more after 10 mm. Gutter on Ledge Wall stays wet for two days whatever the wall does. Wind from the west dries Long Wall and Raven Buttress faster; this estimate leaves wind out.
