3- Allowing lower performance gliders is important from a practical point of view. The 2-33 scare is just that. But why not let Sparrowhawks and such come play? UH A SGS 2-33 is possible but SGS 1-26 is more likely. However, let's use the 2009 Sports Class Nationals as and example. There was an ASW-28 and ASK-14. Both are considered Club Class gliders under the RC proposal. How is a CD going to set a reasonable AT with such a disparity in performance? Sean Franke (HA)







By utilizing the long MAT concept the you refuse to discuss.



Everybody starts pretty much at the same time like AT. They fly the same course, except the low performance gliders skip the last turn so they don't land in a field. It is proven and it works.



Please read what I wrote.

UH, I understand the concept. However, a MAT is NO substitute for AT. Everyone fly's the SAME course in AT. Slower or lower performance gliders cutting turn points is not flying the same course.

Let's pick it apart. You and UH are both right on significant points.

Long MAT and AT have significant similarities. They do feel similar (not by any means identical) for guys of roughly equal performance. The fast guys still win.

They also have significant differences. The legs are shorter on a long MAT.. 180 mile long MAT has a bunch of 20 - 30 mile legs. Maybe the first two can be reasonably long on a good day. AT might be two turnpoints. Result is that the fleet tends to stay closer together on the MAT, there's just less room for deviation on a short leg. It feels different too in that you are (usually) going to get farther from home on the AT, see more terrain and you aren't going to be over the same terrain repeatedly, as can often happen in a long MAT. Some of this can be dealt with by determined and creative task setting.

The races get very different if we task such that you have to fly fast until the end of the day to finish the course. Is this what you want to do? It's probably the way to make the Nats a better training & selection tool for WGC. If we do that, the gig becomes a lot more work, a lot more aggravation for the landees and a lot less barbeque and camaraderie at the airport.
