Unfortunately I still can't find the newer version of the document. .
.here's the old text of my stutterwarp write-up. The formulas are:
        Volume = 2+ (5 * SQRTPower_in_MW)
        Price = volume in cubic meters * .03 million
        Efficiency = (TL+4) * SQRT(Power_in_MW * Ship_Disp_Tonnage)
        Speed = Efficiency * 120,000 KM per minute

I really wish I had the other writeup - I changed the formulas some to
compare better against the standard GURPS star drives. Will keep looking.
Enjoy.

Stutterwarp
To my knowledge, Stutterwarp has only been presented in a gaming context by
GDW, first in their Traveller:2300 (later 2300AD) game, and more recently
in their Fire, Fusion, Steel supplement. It is referred to as blink-warp in
GURPS Space.

Stutterwarp is the closest thing to FTL travel in physical space. It is an
application of the tunneling effect observed in particle physics, an effect
in which electrons move from point A to point B without traversing the
intervening distance and with no change in inertia or momentum. A
stutterwarp ship can literally stop, turn, rotate, and pirouette on a dime.

Stutterwarp doesn't move the ship very far. However, the effect can be
cycled rapidly enough that the ship effectively travels at FTL speeds. If a
human were to view the ship in motion, it would seem like a giant
strobelight was illuminating the vessel as it teleported from point to
point.

A stutterwarp vessel moves its Efficiency in parsecs per day. A ship with
an Efficiency of 1 would take a week to traverse 7 parsecs. In Brilliant
Lances (GDW's starship combat game) the ship moves its efficiency * 4 hexes
per minute; each hex is approximately 30,000 kilometers.

Stutterwarp's mandated limitation is gravity. Its listed efficiency is for
deep space, defined as regions with less than .0001 G. In deeper gravity
wells, efficiency drops by a factor of 10,000, and it requires hours or
days to cross the distance between planets. Stutterwarp cannot operate
efficiently at all in gravity wells of .1 G, and must rely on more
conventional means of propulsion. Thus, stutterwarp will not lift a ship
off-world.

A second limitation is recommended by GDW, and was enforced in the 2300AD
game. Stutterwarp is an incredibly efficient form of FTL travel, and an
invasion fleet could easily bypass picket sensors and hold the homeworld of
an interstellar society captive. Therefore, a second limitation that can be
enacted by the GM is highly recommended.

The limitation GDW gave the drive was that energy buildup occured in the
drive's components and had to be discharged in a gravity well of .1. In
2300AD, the limit was 7.7 light-years, a distance that worked out nicely
for the game's background by establihsing definite frontiers and choke
points along arms of exploration. A vessel could maneuver into planetary
orbit with conventional engines to discharge, and then maneuver outside the
gravity well to continue stutterwarping around the galaxy. Even without
conventional thrusters, a ship could maneuver into orbit, discharge its
energy, and use the celestial bodiy's gravity to slingshot it back out of
orbit.

As far as I can tell, Stutterwarp takes no mass; it is integral to the
hull. There is a formula for the surface area it requires, but since this
is not a factor in GURPS Vehicle design, I have not included it. Assume
that Stutterwarp doubles the cost of the ship's hull and takes up the
listed volume.
