[Healeys] Distributors - 67 BJ8

I fail to see the "advantage" of an adjustable advance curve over the advance
curve engineered by the factory.
How in the world would the average Healey owner without access to a dyno &
other equipment determine if he has adjusted the advance curve correctly. Do
the instructions that come with this distributor shed some light of this? From
a practical point of view how much room for  "improvement" is there when
compared to the original advance curve?

The 123 ignition has the advantage of an adjustable advance curve.
