How big of a difference does it make to extraction times?
People say run 2-3 blind shots through a portafilter but I worry about just going through my water tank so quickly on my machine.
Thanks!

The bigger 'concern' is affect on extraction temperature. A hot pf will not be such a heat sink and give you better maintenance of desired temperature throughout the shot.

Our portafilter is always in the group when the machine is 'ON' and sits in the group after prep while a cup full of freshly drawn hot water is also heating up before the shot is pulled.
My preference is for max temperature stability, group, portafilter and cup.
