What scan tool besides the dealer DRB tool can I used to verify that my sensor sync is 100% correct?

As per service service manual: To verify correct rotational position of oil pump drive, the DRB scan tool must be used.
(10) Connect DRB scan tool to data link connector.
The data link connector is located in passenger compartment,
below and to left of steering column.
(11) Gain access to SET SYNC screen on DRB.
(12) Follow directions on DRB screen and start
engine. Bring to operating temperature (engine must
be in “closed loop” mode).
(13) With engine running at idle speed, the words
IN RANGE should appear on screen along with 0°.
This indicates correct position of oil pump drive.
(14) If a plus (+) or a minus (-) is displayed next to
degree number, and/or the degree displayed is not
zero, loosen but do not remove hold-down clamp bolt.
Rotate oil pump drive until IN RANGE appears on
screen. Continue to rotate oil pump drive until
achieving as close to 0° as possible

I normally use the toothpick method and I've never had an issue with getting cam sync on a motor. I have a DRB 3 and checked it and with the toothpick method it's normally dead on.
 

The toothpick method is show in the FSM, so it should be an accurate enough way to adjust the cam sensor. It's what i have used many times
Finding number 1 cylinder's TDC is the hardest part.
The timing mark, lined up with the indicator, is almost impossible to see on many 4.0 engines.
Paint the 0-degree notch, on the harmonic balancer, white for easier spotting.
 
Curious how this comes about? I've replace my pulse ring in the distributed and all I did was take the old and place the new on. Did I just get super lucky??
