I set mine at 1,000' above the center of the airport so when I see
1,500' above glide slope I just ignore it because I know that I'll hit
sink enroute and it really means nothing. I seem to get palm-sweatingly
low during the final glide but there's always a bunch of lift closer
in. It always works that way... Except when it doesn't.

Bottom line for me is that, though I jump through all the computer hoops
to get that great feeling of knowing exactly where I stand energy-wise,
deep down I know that it's not a perfect airmass and so I trust my eyes,
not the computer.

I used to fly with a built in margin, I have now set it to 0. I think it was set to 800ft, so a normal pattern could be flown when I got home. Then on day my final glide got washed out (literally in the rain) and I really needed to know the correct arrival height. Was it 700ft reserve, 1000ft, what did 300 under glide realy mean? Now when I most needed the correct info, I was doing mental math. I switched that day.

Now on my kobo, I have set my ground clearance height to 1000ft, so my landing amobea shows a ring with reserve, but the arrival is shown correctly.

Lastly, everyone I know that uses a reserve (including me when I used it) would think something like this "I have a thousand over a thousand to the airport".

It seems that a feature that was supposed to reduce pilot workload, was only increasing it.
