Im pretty sure this isn't true due to the exponential nature of drag forces relative to velocity,

It is because L/D max remains unchanged with increasing weight.

but rather is a good approximation for small % changes in weight.

Being exact, it is a good approximation both for small % changes in weight and larger ones. For a detailed analysis and discussion of the topic, refer to your aerodynamics and flight mechanics texts.
