Here is a 50mm @ f8 for roughly 20 minutes. I was going to go longer but that cloud cover was moving right over me so I stopped the exposure. Acros doesn't have much of a reciprocity correction. Other films do. And as a general rule after about 1/2 hour exposure another hour probably won't make for much of a change.
