There is some amazing chemistry going on in modern C-41 films and all that changes over time. I would break out another roll and shoot a heavily bracketed series of a very long scale scene to find the true speed of the film. Or shoot a gray card starting at -5 stops of meter and go up in 1/2 stop brackets which is boring but will tell you a lot about the speed curve of the film today.
