My estimated EI for APHS in bright daylight is about ISO 4 or thereabouts.
I have shot a lot of this stuff. I shoot it at iso 6 and develop it in very dilute (1:150) rodinal for about 7 minutes ( by inspection) with very minimal agitation. There is a shot on my gallery called roadside lake where I have used Freestyle's ortho lith film. I get good tonal gradation with the very dilute rodinal.
