If time is of the essence, consider this.
Essentially you're starting on aggressive ,deep cutting stones then jumping to the other extreme with the Jnats.
A big time saver would be to slot in a 12k HNK after the 5k. You will have refined the edge to about as sharp as it gets, albeit a little harsh. Most if not all your Nagura now become redundant, saving you several steps as that 12 k edge can be finished on your base stone with a few strokes.
