Hi Frank, My review of the massive dev chart is that it doesn't contain N+ or N- information. My shallow understanding of the zone method is that both ASA and dev times usually change to achieve expansion or compression. Perhaps I've missed something on the massive dev chart site that contains this info?

Have you checked the Massive Development Chart? How would this list be different or enhanced from that data already existant?
