Since MA keeps the population constant, it is implicitly using relative fitness. In that case, introducing an arbitrary scaling factor into the fitness doesn't matter; it's only the ratio of fitnesses that matters. It seems to me that the model treats fitness as being relative until it get very small, at which point it is treated as absolute. But there is no simple way to determine absolute fitness from relative fitness.

This seems like a basic point, but I don't understand what the program is trying to model here.

I think the program is trying to model nothing more or less than the complete, abject failure of Darwinian Evolution to produce anything other than Genetic Entropy leading inevitably to Mutational Meltdown, unless the genome is infused with Complex Specified Information from a divine source.
