I should add that I just grind what I need. So I measure up say 40 grams and put it in the hopper and let it grind through. The last few beans seems to go through a touch bigger compared to the rest.
No idea how much real world difference it makes to my coffee though
And on @kboy 's point about it not being the most event grind, is there a better grinder I should be looking at to do the Technivorm justice?
