No, I mean instead of CI's, have a graph that shows N times.

Why not both? A table with a dynamic developmental model that's based on entered variables would be helpful. I believe I saw a CI / Time curve which can also be used to extrapolate development times. You actually need both. The aim CI values are calculated for -1, N, +1, etc, and then the development time is determined using the CI / Time curve.

Small update,
- I fixed a small bug in the tool that led to weird Effective speed calculations. It should now evaluate speed more realistically.
- I added a warning that triggers if your step wedges are too under exposed and therefore can not be properly used to calculate useful data.
- I added a full density table to export to the PDF
- I also modified the PDF "Calculated Data" area, it does no longer state the SBR with flat 0.40 flare applied, It's just not useful.
- Now you will have to add a "reference curve" with the button "Add reference curve" There you have to enter the measurements you got when developing the Box speed curve. It will be used to calculate the relative speed of the rest of the curves.
