I don't have a graph to work with. I'm not even sure where to begin making one without a real densitometer. I also would likely need to read a bit more on how to properly interpret the results!

I've been able to expand the range, I think, just by adding 1 minute to the initial agitation, and developing for 10-12 minutes. A scene that metered from -3 to +1, came out -3 to +2-3 when printed.
Thanks for replying, and for the encouragement.
