Photos vs Logs
Cantsink's final log gives one torque number for each of the 155 piles. For 57 of them, someone also photographed or filmed the tablet screen at the end of the drive. This page puts every one of those pictures next to the logged number, so you can check them yourself. Click any pile to see its log entry, the crew's handwritten sheet and every photo.

These three show a final-looking reading, but nothing on screen or in the file name says which pile. They aren't counted against any pile above.
How to read a tablet photo
- The red number is Murat's markup. The tablet's own “Piling ID” field is blank on every photo, so the pile number rests on that hand-drawn label.
- The time at the top left is the tablet's clock. It runs 11 h 20 min ahead of Houston time, the same on every photo, so 23:34 means about 12:14 pm.
- The turn counter (“Rotations”) keeps adding up from pile to pile and is reset now and then. Two photos close in time can be compared: a pile advances about 3 inches per turn.
- Units changed on 9/24. Before then the tablet read N·m; multiply by 0.7376 for ft-lb. After, it reads ft-lb.
- Targets: 6,667 ft-lb for a single pile, 5,556 for each pile of a pair. The shaft's rating is 7,091. The log copies the screen with the decimal dropped (6,857.9 → 6,857).
