Like I stated in my first post, I am just asking questions.

And I'm pleased to see them. I hope my answers are useful.

When I used the term "pure sailplane" contest I was using the term in the
"purest sense". The rules for Std, 15-M, & Open started as rules for FAI
class sailplanes. The FAI class definitions did not include engines. Motor
gliders were/are a separate class.

They were a separate class, but no longer, at least internationally.
From the Sporting code:

7.6.2 Motor gliders
Motor gliders are integrated into the other championship classes
(except the World Class which is a one-design class) under
championship rules for motor gliders (see Annex A).

So, FAI class definitions now include motor gliders. As an example of
the integration, here is this from Appendix A 7.3 Launching
Procedures:

7.3.2 Motor Gliders Motor gliders may self launch or launch by aero
tow. The Organisers shall describe the launch procedures in the Local
Procedures.
a. If they self launch their MoP must be shut down in the designated
release area below the maximum release altitude.
b. If they require a second launch for a start, they must land prior
to taking the new launch, otherwise they will be scored to the
position at which they started their MoP.

These procedures are what I think we should be using in our contests.

The motorglider class was also removed from the International records
a few years ago, but is retained in the USA for state and national
records. There is a motorglider contest

But through evolution, definitions are
becoming confused.
