To give a further indication of the EI of Efke PL 100 based upon my work with Pyrocat, I have found that for the density ranges that I require for Azo the film will properly expose at EI 100. For the density ranges that I would use for silver enlarging I rate the film at EI 80. Again this is with Pyrocat and minimal agitation.
The choice of developer will have some bearing on the EI. For instance ABC Pyro will not give the same speed as Pyrocat. Also the degree of expansion or contraction will also affect the EI.
I have no experience with Rodinal.
