I've used HSI in pinhole (see the Southwest Wing of my Web page at the
bottom), but didn't bother figuring out reciprocity.  If I remember
correctly, with a Hoya R72 filter and f150, I exposed the film for 8
seconds in June around 2pm under full sun (developed in Rodinal 1+25 68F
6 minutes).  You might consider that a starting point if you're looking
for the same effect as I.
