Some hopefully small viscosity difference from one lot of material to another, in quality materials anyway, is to be expected. How much of a change is considered normal in the real world?

I would say anywhere between 5 to 10% from lot to lot for engineering grade resins is common. Commodity resins may have potential for slightly high variation, maybe upwards of 15% depending on the manufacturer and such.
