Worked: a two-setup run
| Station | BS | HI | FS | Elevation |
|---|---|---|---|---|
| BM | 5.21 | 105.21 | 100.00 | |
| TP1 | 4.02 | 105.36 | 3.87 | 101.34 |
| B | 6.55 | 98.81 |
Check: ΣBS − ΣFS = 9.23 − 10.42 = −1.19 ft, and 100.00 − 1.19 = 98.81. The arithmetic check catches a transposed reading before the answer choices do.
