Start of pump/shot OR more precisely start of shot after "end of
pre-infusion". With a vibe pump this means around 25 plus about 5 to 6sec
(with E-61 group and rotary around +3) from pushing button/pulling up
leverette on E-61 etc.

Hell, you can screw up a build so start of beading isn't until 30 or 60
seconds or even longer! Not long ago switch out the SO grinder to a
different SO and first beading was a full minute with a whopping ~0.5oz
after 2 minutes, so most definetly ya don't time your shots from start of
seeing espresso come down:)

So if you counted 30sec from pushing the button with a vibe right on the
"start of dial it in to taste" money. (Didn't watch the video so don't know
if vibe or rotary...)

Ultimately the quest for Koffee Nirvana is a solitary path. To know I must
first not know. And in knowing know I know not. Each Personal enlightenment
found exploring the many divergent foot steps of Those who have gone before.
