Calculate Adjusted Reduced Levels
Double Run (2BM)
Library command: ~ADJ3
E
This option allows you to calculate adjusted reduced levels from the Level Matrix.
The adjustment method is on a Double Level Run adjusted between 2 Bench Marks.
This adjustment allows for uneven Change Points in the Forward Run and Reverse Run
and weights the measurements accordingly.

We will use the Level Book Example on page 77 as an example.
With reference to the observations between PSM 1 to STN 2. The Forward Run has 3
Change Points. The Reverse Run has 2 Change Points. The Misclose between PSM 1
and STN 2 is divided by 5 and each Set-up is adjusted equally. Therefore the Forward
Run is adjusted more than the Reverse Run in this case, allowing for a stronger fix to the
Reverse Run.
This adjustment allows for Intermediate observations.
Double Run (1BM):
This adjustment does not allow for Side Shot type levelling from the main Forward and
Reverse Runs.
This adjustment uses the method used in Double Run (1BM) first
and then the Single Run (2BM) second.
