Seems to me that one of the things XCSoar should do is intuitively educate
the pilot on what thermal strength they need in order to make progress.
If I've set MC 1, because I'm flying a little faster than MC 0, but XCSoar
"knows" that I need 2 Knots of lift to warrant circling, a Min Thermal
Strength (MTS) value displayed would tell me more quickly what I may not
intuitively understand.
Taking the Condor simulation from Alex, it would be much more valuable to
know that I shouldn't bother stopping to circle for less than 1.2knts or
whatever the magic number is that is better than MC0. You shouldn't need
to play with MC Values to figure out minimum values to make progress. In
that scenario if MTS was calculated with wind drift and thermalling in
mind, I think you'd have a valuable educational element for pilots.
I will commit to trying to develop some scenarios and documented
requirements of a "Club Mode" or something along those lines. Essentially
a set of configuration recommendations for the non-racing XC pilot. XCSoar
is a hugely valuable learning tool for how to fly farther and faster, but
the behaviors need to be intuitive and correct in order to instill
confidence.
Very educational thread, even if I tend to disagree with some of the design
decisions. Unfortunately like Ramy, my C skills are beyond rusty.

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
