Does that make sense relative to your practice of turning off the MC
audio?

Yeah, I have the B-40 audio on all the time set for up only, so it is
telling
me to slow down or thermal in lift. Just isn't constantly giving me input
about
the cruise speed I have chosen. Works for me.

Makes sense to me too. McCready requires an estimate of the NEXT thermals
strength. In the big mountains thermal strengths vary widely so there's no
way to be sure what to set.

On the good side, thermal strengths are likely to be so strong that the
McCready speed-to-fly computation will ask for speeds that far exceed
"reasonable and safe". The maximum turbulence penetration speed (Vb) then
becomes the best speed to fly. Makes me wish the designers would spend some
time raising the Vb speeds instead of the L/D.
