1. Expose 2 pieces of film to a step wedge.
2. Develop normally.
3. Expose one sheet to bright light immediately after developing and while immersing in stop. Probably 100 watt at four feet.
4. Fix that one sheet in the same bright light.
At the worst (or best) case I would expect some measurable "Sabbattier" effect. Based on the anecdotes, I'd say it would be a very close measure.
