I don't fully understand the confusion... I guess I keep it pretty simple in my 
head...

* Higher MacCready = fly faster between thermals
* Therefore higher MacCready = also fly faster even on final glide
* Fly faster = loose more height over distance, thus higher MacCready = more 
height lost on final glide.

All makes perfect sense to me.

It all comes down to the maths for fastest possible time on a task. Which also 
= longest distance if flying further.

You have two choices on final glide on a strong day:

* Leave thermal early, and fly slowly home.
* Leave thermal later and fly faster home.

If the thermal is such that I set my MacCready to 5, then I am going to be home 
faster by staying in the thermal then flying home faster.

So of course MacCready should be changing height home. I just can't understand 
how it wouldn't. Of course it also keeps track of wind which is essential. 
ZigZag is particularly useful home if you have Pitot input especially if you 
have a long final glide and the wind changes as you get lower.

As for flying without a task, I do this quite often. I just set my home point 
as Benalla so I know how far it is to home and how much height I need. If I get 
into the danger zone on a normal task, I can click abort and it will 
automatically set my MacCready to 0 to fly down wind at best LD to find lift.

BTW. I have found an issue with 6.x in that I can't set a task to be a single 
waypoint (e.g. Home). I can use Goto, but then can't save that as Default.tsk - 
so it means I now have to set Goto Benalla each time I turn on my device. It 
would be good to be able to return to some ability to set default to a single 
waypoint for the type of club and local flying people mention.

In conclusion: if you set MacCready to Zero (default anyway I believe) and GOTO 
your Home Airfield - doesn't that give everything you need?
