Theoretically, there should not be a change in friction between inner and outer grooves based on 'linear' speed at the stylus. With dry friction, only the interface between the two surfaces and the amount of vertical weight affect friction.
Since VTF is the same for inner and outer grooves, and its the same stylus on the same vynil, there should be no change in friction merely due to different 'speeds' at varying diamters on a record.
