I think it would be valuable to show how different the gradient might be from a home-made "flash" sensitometer used at low light output (for example time might be 1/10,000 second at lowest setting).

I'd do the test but I don't have the acetate filters to balance the different speeds, and I think you made a set...
Should be easy to do. I think it will turn out OK. The Wejex in the test had an exposure time of 1 sec and the EG&G was set to 1/1000. There was not detectable difference in the way the exposed film responded to development time changes between those two. So, I suspect 1/10,000 would be similar.
