alternative McCready theory and variometers

Then it would be called MC, not equivalent MC. You would set up the real MC
you are following on the vario which is obtainable on many instruments that
send to the PNA this setting every time you change it (LX V7 for example).
And for the purpose of giving you some information you dont already know
(the MC you did set manually) it would be useless: you would never know what
you are really doing.
Despite you have set MC to 1ms, you are flying much faster because you are
in sink since some time.
Some people think that after a long sink we can expect a "long" lift, but
generally they outland if they dont do a 90 degrees turn and run away the
sink area. The loss of altitude has to be accounted as a pure loss with no
gain expected for sure.
The precaution you mention is the STF audio that since decades already does
what you say.

No, I totally would want it to be adjusted for sink and climb.

LK8000 doesn't adjust for that, so it's probably not a good
example/definition. What I meant is "flown MC". Its reversing the STF
calculation and producing a figure from averaged airspeed, the polar and the
rise/sink.

Also as a precaution against a common mistake of flying so slowly in sink
that you're actually achieving smaller then maximal achievable L/D I would
like to have immediate warning for that (spead up!).
