I'm trying get an idea of what you mean by "accurate" STF commands. The

top contest pilots I've followed seem to fly pretty steadily - will it

give me the STF that a top contest pilot will cruise at? That's what I

would call "accurate"!

I tried to tell that without accurate info on vertical airmass movement you can't have working STF command. This is where inertial system seems to be very good at. Sorry if I was unclear about this. Without good STF you would probably fly with predetermined still-air mc-speeds. Sure it works also, but it is not optimal. Plus if you know the airmass movement you have a better idea where to fly during glide.
