This is currently hard-coded to 0.5:

This also shows up in housing benefit:

Perhaps the deductible pension contributions could be its own variable, based on the policy parameter.

Yep I agree. There's also a lot of places where variable formulas could do with a bit more abstraction (applicable income for benefits, many other places).
