The drizzle stops around 9 AM, but the very low clouds are still here.  Should be warm and dry the rest of the meet.

Results should be up at http://www.dynamicflight.com.au.

Since I have access to the most recent version of the 2002 Australian Nationals data (after a few fixes) I have the opportunity to compare the results using the OzGAP and the GAP scoring system.  Of course this after the fact analysis doesn't change the perception that the pilots had during the meet that they were being scored using the OzGAP system.

So we have a comparison that says what would happen if we told the pilots that we were using the OzGAP scoring system to score the meet, but after the completion of the meet we'll score it using both scoring system.  Would it make any difference after the pilots can't make any difference?

Here are the first thirty places:

Well, I'll let the reader be the judge on how big a change the OzGAP scoring system introduces.

Tim writes on OzGAP in the next article, and amazingly enough I might have even further analysis and a slightly different scoring system to review in the near future.

Some more facts about OzGap to help pilots plan their strategies,

1. Arrival points in GAP and OzGap are calculated exactly the same way.  What most people don't know is that arrival points are based purely on the order you cross the line.  If you are second arrival over the line, you will get the same arrival points whether you are one hour or one second behind the first arrival.  However, in OzGap, arriving much earlier will improve your departure points score.  In GAP your arrival time doesn't affect your departure points score.

2. The number of departure points available in GAP and OzGap are the same.  It is just easier to get them in OzGap because it is not dependent on your speed.

3. On a long day (eg Hay last day), the departure points will have much less effect on final scores.  The time difference between the lead line (full departure points) and the zero line (zero departure points) is a quarter of the winner's time (5 hr 28 min /4 =82 minutes ). An OzGap 'feature' is that on a 'short' day that ends up being a long day such as the last day at Hay, OzGap encourages pilots to leave early, and then they have a much better chance of actually making goal before sunset.

4. With OzGap, you can actually start later than in GAP and get the full departure points.  In OzGap, if you start early enough that you are first into goal, you will get full departure points.  In GAP you have to start first.  This means that with OzGap, at the start line the guns only need to watch the other guns to work out who is likely to arrive at goal first.  This is much easier and more reliable than with GAP where at the start line you need to watch the entire field to determine which of the very early starters are likely to make goal at all (which is a similar decision to choosing lotto numbers!).

Details of OzGap can be read at: http://www.triptera.com.au/canungra/classic2001 and a pdf explanation document downloaded from: http://www.hgfa.asn.au/Competition/manual/departurepoints.pdf

Hansjoerg Truttmann «Hansjoerg.Truttmann» writes:

Here is what we've seen after 10 tasks in the Swiss League 2001. The results are similar to what we found in the German League.

· The Swiss League 2001 consists of 10 different tasks.  Rigids and flexxies flew the same tasks at the same time during all the tasks.

· I didn't take into account task 5, where nobody reached goal and the best rigid flew only 19.5 km and the best flexwing 12.5 km. I don't have the number of league-pilots in goal from task 6 to 8 which were flown during the Swiss championships but I have the average speeds of the best pilots (out of an earlier analysis, see (https://ozreport.com/5.97)

· The competition scene in Switzerland is pretty small nowadays.  In the Swiss League we saw between 5 and 9 flexwings and 10 to 12 rigids.  More rigids than flexwings btw.

· Are the pilots' skills of about the same level?  I think they are not far apart, the rigids being a bit better over all perhaps.  In the flexwing-class we have former Swiss champions like Martin Härri, Franz Hermann, Kilian Raemy and internationally experienced pilots like Nichele Roberto, Oliver Kälin, Tony Marti (who only competed in task 2).

Martin Härri didn't fly task 1, 2 and 5 and Franz Hermann didn't fly task 1, 2 and 4. Among the rigid wing pilots we have Michael Huppert, Juerg Ris, Richard Meier, Diego Bussinger, Hansjörg Truttmann and René Leiser.  They did well in international rigid-wing comps in the last two years (world team champions, Diego leading the world ranking for a while, worlds bronze medaillists etc). But none of them realized top results during their flexwing careers and none of them ever was Swiss flex wing champion.

· All the best rigid wing pilot flew Atoses.  Among the best flexwings we had Litespeeds, Laminars and Talons.

In the first 8 tasks there was no Atos-C nor Atos-C-prototypes among the rigids.  Within these tasks almost all Atos' came right off the shelf except that the best were equipped with profiled base tubes.  No extra weight was used either.

Short summary:

Over all, the winners of the rigid wings class flew about 25% faster than the winners of the flexxies*. Rigid wings reach goal much more likely than flexwing pilots (avg: 45% in goal vs. 17%). We had quite extreme cases (task 2, 9, 10) where none or only one flexwing reached goal but at least half of the rigidwings.

As I mentioned above, in Switzerland we have more rigids than flexwings in competitions.  I think, now we know why.

I start keeping track of the US pilots' points for the 2003 ranking starting in January 2002. I use the pilots' best two scores for 2002 and then add their two best of 2003.

As a number of pilots who were in the top twenty in US ranking have come to Australia they get the advantage of adding their points from the Australian meets to their overall total.  Other US pilots who are stuck at home have only their best two meets from last year to make up their NTSS total (so far).

If you look at each pilots' best two meets from last year and compare them with their scores this year, you get some idea of how well they'll be doing in the scoring after the meets in April when the rest of the top twenty US pilots will be flying against them.

Notice that Paris will probably only use his top finish at the Australian Nationals in his 2003 NTSS score (the top four scores). Same for Mike.  Jerz may use both, but one for sure.  Chris will use at least one if not both.  Kari got her best points at the Australian Nationals and will very likely use that score.  James can use his score.
