Nope, the Pertronix can't fix worn out distributor bushings! The unit is a
good basic design.
However anything man made can fail.
Over the years I have seen many, many more of the Allison/Cranes fail - both
the opto unit and
the control box, so I won't use them anymore.
The Pertronix can also be used to trigger an MSD. I dynoed an engine to 8500
(it stopped
pulling well at about 7900 due to the cam grind) with that system. Ignition
was never an issue.
Any inaccuracy of the Pertronix unit is negligable compared with all the
mechanical monkey
motion of the chain/cam/spindle/distributor advance plate. This is why crank
fire is desireable
for racing and nice for the street (though certainly not required).

I've actually had mediocre luck with Pertronics.
It worked all right, but with a somewhat worn distributor, I still had
some timing wander. Got an Allison (now made by Crane,
www.cranecams.com) which uses a (less durable but more accurate and
still cheap) opto trigger. It seemed better, and the ignition timing
stabilized. I know, I should just rebuild the dizzy, but this was a
quick fix that let me drive the car that afternoon!
It's more involved than the Pertronics unit, and the opto sender can
fail or get dirty, but it's worked better for me. I still carry points,
as a backup, along with a spare sender.
More options,
Toby
