Hope you are having fun shooting Wyoming!
I am working on a revised graph of your data with a compressed LogE scale in the toe to counteract the effect of flare.
I think it's the necessary approach to graph a test that was shot with flare.
One interesting thing my new graph will do. I will end it abruptly at the speed point for 320. That's because effectively flare guaranteed there isn't any step wedge sample that received "less" light than that.
