  I can't think of one off hand where the dynamic timing is not
availible. It may not be in the owners manual, but it is availible.

IF the car is original and IF the dizzy is the same specs as the one the
timing was configured initially then your generalization may be accurate.

 MG in it's infinite wisdom installed several different distributors in
the B series engine (as well as the A series) over the years, most of
which are physicaly interchangable, but had different  advance rates,
total advance and different vacuum advance units. Add to that the
variations for various markets, and you get a BUNCH of availible dizzys.
Only one of which is "correct" for a given model.

That is the whole point. there are too many possibilities for one of our
cars to have the "incorrect" distributor or advance curve to say that the
static timing is anything more than a starting point. 
 Given a bog stock engine, the manufacturers spec for dynamic timing is
the final figure to use and let the static timing fall where it may.
After all, how much trouble can  static time that is out by 4 degrees do
to an engine that is not running. 4 degrees off on total advance could
cause a bunch of problems on an engine that is running.
