alternative McCready theory and variometers

Hi,

The "alternative McCready theory" has been around for decades now. http://www.tbss.us/txfiles/Kai_intro_XC.pdf
It's not opposing McCready, just making a strong case for steadier inter-thermal speeds. But as I'm reading it, it makes the speed command feature superficial.

Is there a variometer manufacturer that doesn't ignore that?

My ideas for features:

* showing equivalentMC http://www.lk8000.it/new-20-features...t-mcready.html
* automatic MC set from equivalent MC

Getting rid of speed command would mean you could have something useful in cruise mode instead. For audio I would probably choose:

* relative netto variometer indication with dead-band.

and more....

Any comments?
