What I've noticed is it's heavily dependent on the dishwasher.
I've not had the privilege of having a new dishwasher till my most recent place, all the dishwashers prior have been 10+ years old. This new one though which is a Miele dishwasher has maybe 1-2 dishes that need to be manually washed per week at the very most. Whereas my older dishwashers it was anything from an extra 1-2 dishwasher loads per week worth of failed cleans.
