I should have said that I am using Geant4 9.6.1, though it won't effect this.

Turns out this was my problem. I was trying to just create a purely linear relationship (just like the standard SCINTILLATIONYIELD parameter), but I did not take into account that it would not extrapolate with the same linear relationship. With a wider range added, the relationship matches what I was expecting to see.

In the shown code, I just tried a linear relationship, but going forward, the photons/energy-deposited metric for the various particles is being taken from the work of Cecil et al. (https://scholarworks.iu.edu/dspace/handle/2022/2961). Hopefully applying these at a rather small step spacing and including the entire energy range will go smoothly though I will also include the spline fitting and see how much additional processing time that adds.
Thank you for your time.
