On the other hand, such a large chute won't purge as a FIFO (first in first out) queue... some of the fresh grinds will come out as you purge, and there will be some degree of mixing between the stale coffee and fresh coffee.
The Mazzer doserless screen design intentionally creates resistance for the exiting grounds, so I would expect them to have more retained grounds and mixing of new/old grounds in the chamber than the doser models without the screen that eject grounds with impunity. Even with aggressive sweeping of the Robur's chute, a good single's worth of coffee is wasted before a grind setting change is fully in effect.
