From Jim Cavanaugh's article from Pipers Magazine: (noted at the end of your
post)
"His technique is to accelerate the airplane to 45mph, quickly pull in two
notches of flap, count to two and pull the wheel back into your stomach. "

I think he's referring to Art Mattson's high performance take-off
procedure
for Cherokees.

Dave must have some information additional to that provided on the web
site, as is see no mention of moving the elevator to the stop at
rotation:

Short Field Takeoff Procedure
Getting the best short field performance out of your Cherokee begins
before reaching the end of the runway. This requires leaning to
slightly rich of max. power at your runup. This is achieved by leaning
to maximum static RPM and then richening the mixture slightly as you
would at your cruise altitude. (If you plan to cruise more than 2000
AGL, you will need to further richen the mixture.)

Never stop on the end of the runway. After you are cleared for
takeoff, make a rolling turn onto the runway-no flaps. When you reach
an angle of 45 deg. to the runway, start accelerating so that by the
time you have completed your turn, you are at full throttle.
Accelerate to your predetermined rotation speed (this is between 45
and 60 mph depending on mods, temperature and loading), at this speed,
pull in 2 notches of flaps, count 1.... 2 and rotate! You can take
your first notch of flaps off fairly soon after gaining some speed and
take the second one out as you continue to gain speed.

This procedure is like adding 300ft+ to the runway which reduces your
"pucker factor" for clearing obstacles. Practice on a longer than
needed runway and get comfortable with it before doing it on a short
field. I use this procedure on all takeoffs regardless of runway
length, as I go into short grass strips regularly and want the
procedure to be second nature. By using ths [sic] procedure, you will
quickly discover that your Cherokee is capable of more than you
realized.

For a first-hand account of how well this works, read Jim Cavanaugh's
article from Pipers Magazine.
