Here is my selective 500 meter stats from the GPSSS site.
Western Aus States (pop 22 million), 19 sailors over 40 knots for 500 meters.

In the far poorer, smaller Eastern Island State (NZ),
with no "Sandy Point status" & no "consistent wind"
~ 8 sailors have exceeded "40 knots for 500 meters".
5 of those 40 knots Sailors used KA Koncepts & 5 home made boards,
What is most surprising from the homeland of Carbon Art,
Not one Sailor used a Carbon Art speed board.
All but bar 1 of these 500 meters was recorded many moons/ 500 meters ago.

For GTC to be fairer, 500m should be included!
If the Far Eastern State weather returns back to normal,
NZ may be able to compete in the GTC & the 500 meter will make it fairer comp.
We know 500m! Its here to there.
Time of 10 seconds, can't see, can't feel!.....
Bring on 500m to the GTC!
Tradition can not be discarded!
