Seems like a pretty good test to me.
Not seeing the range of which the posted results are typical, but having played
the sheep game, I'd guess that the EVF
delay is less than the variability in test shots. If so, it should have very
little practical effect.
The shutter shock delay is the big factor, as one might expect.
Results varied with tester, camera and lens, but I don't recall any trouble
below 1/60 and some found none below 1/100.
The high end seemed to be around 1/160 for most. That's a range that may be
avoided pretty easily in many situations, if
paying attention.
With the 1/8 second delay set, one may switch it on and off very quickly. With
the Super Control Panel activated, a push
of the OK button brings it up. Touch the Drive setting icon (or navigate with
buttons), press OK, and you get a range of
settings along the bottom of the LCD. Those with a diamond next to them have
delay on, those without, not. One click of
an arrow key changes it.
If you leave the icon highlighted during a shooting session, just press OK
twice and the appropriate arrow and shoot.
Sounds a bit convoluted, but nowhere near as much trouble as going into the
menus. Less trouble to do than to describe. :-)
I imagine one can assign delay and no delay to user settings, but I've yet to
figure out how those work. It seems to not
be as straightforward as cameras where a group of settings is applied to a Mode
dial spot.

What if the Hokey Pokey *IS* what it's all about?
