Once again GEANT4 is correct and my use of it was the problem. Turns out air (with a refractive index = 1.0) is a really good cladding material. When I artificially set air's refractive index to 2.0, my simulation accurately produced the manufacturer's specified trapping efficiency of 3.8%.

Apparently I need to include a boundary condition that accurately represents wrapped fibers.

thanks for your help, looking at photons one at a time, lead me to the problem.
