Ok, CV will change to "no more then three visits" and add "performance". Thanks. Amended 1.4.5.b then becomes:

1.4.5. Distance performance for badges only
b. Distance using up to three turnpoints:
A flight from a startpoint via up to three declared turnpoints to a finishpoint . If the finishpoint is the landing place it need not be declared. In any sequence, no more then three visits to declared turnpoints may be claimed for the performance.

With this definition it is possible to declare three turnpoints and:
1. Visit no point at all i.e. make a free flight to a landing place
2. Visit one turnpoint and return home or land anywhere else
3. Visit two turnpoints and return home or land anywhere else
4. Visit three turnpoints and return home or land anywhere else.
5. The sequence in which declared turnpoints are visited is up to the pilot.
6. It is not possible to visit more then three turnpoints because of the "no more" rule. So "yoyo-ing" is not possible.

Your examples are correct. Since startpoint and finishpoint are no turnpoints a flight like S-A-S-B-F-C-F is legal in the original FAI rule (see the Code) and in my amended version (6 legs, i.e. and average of 160 km per leg for a 1000 km flight, so nothing wrong with that).
Usually a flight will be planned like S-A-B-C-F or S-A-B-A-F or the ones you indicate.
Turnpoints at the same spot are like identical twins; you can give them different names indeed.
The last part of the performance is basically free indeed.

Regards and thanks for your attention,

This is it. Cannot find anything wrong. Please shoot at it.

Well, you could change "not more then up to three visits" to
"no more than three visits" or "a maximum of three visits".

Also, this seems to leave open the possibility of rounding
the turnpoints in a different order than declared, and even
of skipping one declared turn point !? (You could declare
A-B-C and then fly A-B-A, or maybe even A-C-A, B-A-B, B-C-B,
C-A-C or C-B-C) Was that what you intended ? Or is this
covered somewhere else in the rules ?

It seem a little messy to talk about "visits". Why not just
treat TP3 as a different turn point than TP1, even if it
happens to be on the same spot on the map ?

BTW the rule about not having to declare the finish is interesting.
It would seem you can visit your declared TP or TP's (1 to 3) and
then basically treat the last leg as a free distance. Is that how
the rules stand today ?
