Yes, grind is a possibilty.
I think the single biggest contributer to consistency is a good routine.
You seem to have a good one established, the only other thing that might be worth a play is how you dose your PF.
There is a style of dosing which Chris (2muchcoffeeman) teaches called dose & collapse.
Whilst filling your basket, tap the PF on the bench lightly a few times
Then do the rest of your steps.
This will pack just a little more coffee into the basket. Not much, but I find if I stick to this, I get drier pucks.
Hope that helps.
