I'm not a comp pilot however I know that all the data in the world is of no use
if you can't interoperate it and use it effectively regardless of what your
doing; there are pilots and there are aviators; pilots drive aircraft through
the sky, aviators fly as they were born with wings; when was the last time you
saw an eagle looking at his vario?

Roger,
I'm not sure about the definition, (and it is five years since I flew a
nationals so not sure I qualify) but I believe that a good Relative Netto
averager in cruise is crucial. Preferably with a numerical display to one
decimal place, 20 second average (an S-nav was my preference but others will be
fine too).
I have a view, for what it is worth, that we instruct thermal technique (some
instruct it better than others) but there is little or no instruction on cruise
technique. I mean the optimisation of cruise to maximise cross country speed
not the basics. This is one element in a bigger picture.
The relative Netto averager was on my home screen, switching to TE for
thermalling. I had it switch based on GPS heading change. All possible in a
25yo S-nav with 12-13yo firmware upgrades connected to a GPS-nav. The averager
was part of my scan, and I would recall trends and fine tune subtle direction
changes to pursue rising trends. I had to be really current to do this well,
but it isn't as clumsy as I write it - it was automatic, a situational
awareness thing. I developed this technique after flying with Georgio Galetto
in a Duo one day (more piecing fragments of advice together, but he insisted on
using Relative Netto average too). I have heard others use terms like "energy
line" but that sounds too BS for me.
Of course, this information is academic if you aren't skilled at the rest -
and it must not compromise lookout. And if there is a big fat cu ahead,
concentrate on where you think the best lift is under it. And if there is
another glider cruising nearby, use them as a reference (best indication of
another part of the airmass, that is why team flying works). However it worked
well for me when racing alone on a few blue days.....
Cheers

Dear Tom and others,
Sort of related ....
Do you operators at/near the top in Nationals favour using while cruising a
vario set to relative mode, ie showing all the time what happens if the glider
were slowed below 60 knots, in effect airmass less glider rate of sink at 60
kts?
Cheers

For myself, I am not interested in any variometer cruise modes so
am content with my B400 and B40 in our second glider. Interestingly both Bruce
Taylor and myself seem to muddle along OK with sink tone disabled!

Mark,
The idea is to fly in air that's going up. You should not be
hearing the sink sound much. If you are it is time to go somewhere else and be
in cruise mode while doing this when you won't hear the sink sound.

poorly. It is extremely important when trying to center weak and broken
thermals which is why I like a vario with a sink sound as it provides full
information on the bad air as well as the good air while doing this.
And on that note, I'd like to congratulate you for the B50,
which, as installed in AUGC's H205
Club Libelle, had the most inspiringly depressing sink sound I've
ever had the misfortune to
hear.
Excellent work, well done :-)
