Set a Comandante C40 MK4 to 15 to 25 clicks from zero for V60 pour over, per Honest Coffee Guide's compiled C40 chart; the wider pour over window runs 16 to 34 clicks. The community default of low 20s sits right in that band, and 2 click moves are the right dialing step.

Every numbered range above was checked against the source in the footnote it carries; where a manufacturer publishes nothing for a method, the row says so instead of inventing a number. Ranges are windows, not verdicts. Beans, roast age, and dose move the right setting inside each window, which is why the dial-in ladder below matters more than any single number.
How the Comandante C40 MK4 adjustment works
The Comandante C40 MK4 uses a click ring under the burr counted in clicks from fully tight (zero); about 30 microns per click and roughly 1090 microns of range. Find your zero before trusting any chart: with the hopper empty, tighten toward fine until the burrs just touch, call that zero, and count from there. If your zero point is calibrated differently from the chart's, every range shifts by the difference, which explains most "the chart is wrong" complaints.
Dial it in from the chart in 3 steps
1. Set the middle of the pour over range above and brew once, changing nothing else. 2. Taste against the two failure directions: sour, thin, or fast means grind finer; bitter, harsh, or stalled means grind coarser. The full logic lives in why espresso runs sour and why it runs bitter. 3. Move in small steps, one variable at a time, and write each attempt down; the free dial-in logbook exists for exactly this, and the printable dial-in cheat sheet keeps the correction table next to the machine.
