Processing Leveling Data

[CS06]
I find the help section on level reduction a bit lacking and confusing.
The example file (Pg202.lev) appears to have a fatal flaw in line 8 with a
BS on an ER "end" ... but this mistake is ignored by the program during its
adjustment.
Since the help doesn't explain much I decided to play with the routine, even
recreating the data shown in the example. To my surprise, the program does
not appear to recognize the "station" field as meaning anything. Entering an
elevation for an earlier appearance of a station does not produce the same
value later in the file, whether as a starting point or a closing point.
Please correct me if I'm wrong, but why is the ER record on station C (line
28) using the pre-adjustment elevation of 106.25 instead of 106.275 as
determined on line 11? The same apparent error is repeated on lines 19 and
20 where pre-adjustment elevations are constrained to.
In types; Start, Turn, Sideshot, and End ... what is a Description Shot?
Appears to be associated with adding a note, but I'm guessing I'm missing
why it looks like a shot in that it allows each field to be used.
I can't find an explanation of what the 2 possible Code items mean/do. EL
vs. FE? Didn't seem to have an effect on the values produced.
It appears that storing the points to a CRD file replaces the value of any
points in the CRD file with matching names (ONLY if they already exist). Out
of curiousity I added some extra different values and found that it takes
the last listed elevation and uses that alone in replacing the elevation
value.
Is this format something that a particular digital level exports?
Thanks in advance for any input.
