I started off weighing the whole beans on a gram scale and single dosing. It works, but I don't like it as much. To its credit, the Vario doesn't popcorn a whole lot, but it definitely grinds less efficiently when it's down to the last few grams in the hopper. I feel the grind quality suffers slightly when single-dosing. And you completely lose the killer feature of the Vario, which is timed grinding to a tenth of a second. If you fill up your hopper with one coffee, you can dial in pretty consistent doses with the timer.
Also, when switching from caf to decaf, you'll want to sacrificially grind a bit of decaf to purge the last bit of caf out. Retention on the Vario isn't much, but pulsing the empty grinder does not purge it completely, I find.
