  In 2011 Radyushkin outlined the practical implementation of the One-Component
Double Distribution formalism in realistic Generalized Parton Distribution
models. We compare the One-Component Double Distribution framework to the
standard one and compute Deeply Virtual Compton Scattering observables for
both. In particular the new implementation is more flexible, offering a greater
range of variation of the real and imaginary parts of the associated Compton
Form Factor while still allowing to recover results similar to the classical
approach. Moreover the polynomiality property is satisfied up to the highest
order. Although the comparison to experimental data may be improved, the
One-Component Double Distribution modeling is thus an attractive alternative.
