Range is greater at 3kts than at 8kts, but it takes longer to get there. Thus the 8-9kts recommendation is balanced, taking into account fuel usage and travel time. If one is solely concerned with maximum range (getting home on low fuel e.g.), then one should run at very low speeds.

Do I understand it correctly?

Fuel economy is a function of how hard your engines are working, not speed. If you set your speed to a certain value, your actual speed may well be less due to bad weather and the effect of waves on your boat.

I've also done the bell-curve calculations for all boats and came up with the Fuel Economy mod. I tend to cruise everywhere on Ahead Standard but switch to the fuel economy setting if my patrol grid is a long way from home port.
