Of course not but it is still personal a personal

be opiniated, there is always more than one way to skin

Try it the other way, you'll see.

After 40 years of using a 1000' arrival height as my
"aim point", I
probably
shouldn't be changing it now :^)

But, I have always added a few hundred (or more) feet
if I thought there
were
going to be difficulties at the landing area, or (rarely)
subtracted a few
hundred
when close to a landing place that had no problems,
and the extra search
time
might find me thermal.

Probably shouldn't comment but anyway..

Setting a fixed margin and then doing airborne sums
based on the current situation and that (remembered)
margin, is more difficult for me than just setting Zero
and seeing what AH is predicted on screen.

When I look at others' LXXXX devices I often find they
have 628feet (aka 200m), which suggests they may not
know what margin is set and indeed may never have
looked at the page.

Zander ZS-1 had the answer - AH welded at zero.
wysiwyg.
