Good day to everybody on the list,

Another Wch is over and I would like to congratulate all winners (individuals and teams, juniors and seniors) for their great success.

Also a big thank to Jojo who turns to be the official F3J webmaster.

In the past collecting the data from the result I did some statistics in order for all of you to look at some summarized data but also to find whether there something that we can do regarding the scoring of F3J.

So here we are.

Here is a table for the flight time.

Those data represent the number of competitors by rounds (horizontal axis) and by flight time (vertical axis)

After that there is a table regarding landing bonus.

On the last column there are some percentage totals so also from this Wch we can see that 87,59 % of all the flights landed within 5 m from the allocated spot.

Here is also a comparison between 2002 and 2004 Wch.

In the past there have been a lot of discussions here in this forum and also at CIAM’s soaring committee

What I can see from those statistical data is that most of the competitors are flying 9.54 to 9.50 regarding duration. And if you know this class you can easily say that if there is a decision to increase the flight time let’s say to 12 minutes for the preliminary rounds the percentage will be almost the same ie most of the pilots will be among 11.54 to 11.50. Of course this is a strictly personal estimation and I will be very glad to see some other thoughts as well.

So what I can say is that there are not so many things we can do regarding flight time part of the competition.

But what I can see examining the landing bonus table is that there is a room to do something for that.

What I propose is the following.

That means 20 cm from the spot 100 points over 5 m from the spot 0 point.

Of course for the time being this is only just a thought which I share with all of you and waiting to hear some additional ideas or comments on the above.

I would like to wish all the best to all of you from the Olympic City Athens.
