I'm confused that in a diagram on the page, the BGR LED frequencies (particularly R) don't seem to all align with the peak sensitivity frequency of the film. It still seems like you would want a broader sampling of light. Post-processing, regardless of the math involved, is cheap.

The light source wavelengths don't need to align with the density peaks of the film, they just need to be far enough apart to isolate the individual dye layers and avoid the overlap between the camera sensor channels. Using 700nm for red would be challenging as most digital camera sensors aren't all that sensitive to 700nm.
