Even semi-commercial machines need a few shots at espresso flow rates to find their groove. Someone needs to invent an inexpensive reusable puck or restricted-basket to make pulling blank shots convenient.

For the last while, I've been collecting up the grinder purges through the day and pulling tomorrow's 1st shot with them. Directly into the tray! Let the group sit for a bit to allow the coffee to 'work'.
For the non-purging Pollyanna / miser, a few grams in the blind basket works as well.
Not quite a quantum leap, but the delta between 1st and 2nd consumable has diminished considerably.
Same improvement on the HX and DB.
