Small....I'd say variable, rather than small.

Just depends on driving type at the time, type of clutch etc etc

Sometimes you might be able to make it pretty smooth, others not. But a lot depends on overall drivetrain to. If everything is fairly tight, box rubber mounted etc then any clunks would be less noticeable anyway.
But you can never expect it to be as smooth as a synchro box. But then a full manual synchro box will never shift like a dog box when racing.
