Like this
map
DeckExtensionPlanMap -title "The Deck Extension<br>Upper
Levels<br>
…
36-BigWednesdayPlan@MiddleEarth
36-BigWednesdayPlanCL@MiddleEarth
…
end map
where the contributory maps look like this…
map 36-BigWednesdayPlanCL
-title "36-BigWednesday centreline Plan" -projection plan
36 #centreline survey
endmap
map 36-BigWednesdayPlan -title
"36-BigWednesday Plan" -projection plan
36-BigWednesdayPlan-s1 #scraps
36-BigWednesdayPlan-s2
endmap
So what it is looking like, if the contributory
maps are all derived from scraps (or maps in turn derived from scraps), then
the altitude range is correct.
But if there is a map that is centerline derived
(ie has no scraps) then the altitude minima is set to zero.
One other thing.
All my tests so far use survex for
loop closure. I have not tried using Therion loop closure.
And all my files are native Therion files –
no survex imports.

I checked and I can confirm what Bruce is saying. If you don't include
centerline in map, the altitude range is correct.
If you hide the centerline in the layout (leaving it in the map) the
altitude range keeps starting from 0 m.

I am not seeing this Bruce. I just tested with 5.3.16. My survey
imports the centreline from a Survex .3d file however, so that might make a
difference? Or maybe I am not understanding what you mean by including the
centreline in the map. I turned off the centreline using 'symbol-hide line
survey'. If I comment that out in my layout then the centreline is drawn in the
map, but my altitude range still covers only the range of my scraps.

OK, the problem is not the previews or the offsets, as it occurs in
the map examples below regardless of presence of previews or offsets.
What does seem to control whether the altitudes start at zero meters
is whether the map definition includes a survey centerline.
If part of map definition includes a survey centerline, then
altitudes are coloured from zero meters to survey maxima (a bug?).
If map definition has no survey centerline as part of it’s
definition, then coloured from survey minima to survey maxima (correct
behaviour).
Hence I find this behaviour manifests in maps in progress, but when
they are finished and I (usually) turn off the centerline maps, they correct
themselves.
