Let's suppose you do your gold height during your 300km diamond goal flight.
The claim for the height gain is not restricted to the time between the
start and finish of the goal flight. They are two separate claims. The
'soaring performance' with regard to the height claim begins with the
release from tow. The 'soaring performance' with regard to the diamond goal
claim is from the start point to the finish point.

What an amazing bunch of self contradictory stuff the Sporting Code is.

The first and second sentences of 4.4.1 seem to contradict each other.

4.5.3 says altitudes are taken from pressure data except for the odd 
case of flight continuity.

Release point is defined as a point on the ground but start time and 
altitude may be taken there? The altitude there is zero feet AGL 
according to the definition.

"Soaring Performance" is from the START point to the FINISH Point.

Gain of height is difference between high point and previous lowest 
point DURING a soaring performance.

Does "during" actually include the start and finish points? If not 
then you cannot use the release point for an altitude claim and need 
a subsequent lowest point.

Note that the rules for mechanical and electronic barographs all 
require a notch on the P.A. trace or record and any evidence must be 
such that it is of the standard as if it was the ONLY evidence.

Beats me.

There's also a bit about if there's any doubt it be interpreted to 
the "maximum disadvantage" of the pilot. I would take this as 
disallowance. Even if not, the "low point" is going to be higher than 
it otherwise might be or you think it should be. Exacly where during 
this turn after release did the release take place? No problem if 
there's a good margin on your gold height claim but to do that at 
most places in Australia where gliders are flown would require a 
climb to in excess of 13000 feet if you do a normal 2000 foot launch 
and continue to climb in a thermal without a low point.

In the end it will be YOUR failed claim.
