For what it's worth, my new Rocky's zero point is at "zero" as well!
It's my first experience with a doser, and I must say it seems like a mixed blessing. I certainly like the concept of grinding into a hopper, and then dispensing from that, but I'm a little dubious about the concept of measured doses when grinding small (unmeasured) quantities of beans. If I grind for a double shot (or more), then the flow from the chute falls mainly between the vanes of the compartment directly below the chute outlet. Some cascades into the compartment to the left (as you look at it), but some, more importantly, falls into the compartment to the right. When the doser is used, the first delivery is always a short measure from the partially filled compartment. This negates any concept of measured doses with my operational method.
Certainly, this first shot could be collected in a bowl and replaced in the hopper... but this seems redundant on a doser model. So, the concept of grinding and pulling the lever a couple of times for a measured amount of grounds is lost on a low volume uses who grinds approximately the correct amount each time.
A simple modification that provides a barrier on the right side of the chute is being contemplated. It shouldn't be to difficult... a small piece of stiff plastic sheet cut to shape should do it. Anyone done it already?
As mentioned earlier in this thread, it is best to drag the lever continously while it is grinding and stop when you see the filter is slightly overfilled, swipe excess back into doser (if you are going to use those grounds in a short time) with finger, tamp, lock and load.
Each dose is too small anyway (6 grams I think?) and will lead to underdosing (is that a word?) in almost all cases. Much better to overfill and swipe.
The doser will however come in handy in those cases where you are serving to many people. Then you can let doser just grind all the time while you're pulling shots.
FWIW - When dosing I take two measured spoons of beans and grind those. I then dose the result into the PF. That will give me a slightly overfilled PF which I then tamp, lock and load. Doing this takes a lot of the guess work out of the equation and I grind only what I need.

First off let me congratulate you on your purchase. I own a doserless Rocky, and have been using it for a for a month now, It’s zero point is zero. However, I have been finding that with espresso my grind setting is between 9-13, depending on the grade and age of the beans. As most will attest to: You must find the setting that works best for your situation by trial and error.
I have been reserving the first pull of the day for myself so I can see which way to adjust the grind; usually it is only one click up or down from 10. I have found it sometimes takes a little more trial and error when using a new blend of beans.
