Tilt-up standings

Travel is how far the crane drives, divided by the panels. Luff is how far the hook moves in or out between picking a panel up and setting it. Slew is how far the crane swings with the panel on the hook. Turn is how far the panel itself has to be spun on the hook to face the right way on its footing; a panel cast with its top facing the wrong way needs half a turn, and that is the layout's fault, not the crane's. High-risk picks are the picks the plan's own safety checks mark in red in the video.

TIQ reads like an IQ: the average project scores 100 and higher is better. Each project's motion is weighed against the average of every project on the board — travel counts three times, luff twice, slew and turn once each. One standard deviation less motion than average scores 115; one more scores 85. Then the high-risk picks scale it: a project with a quarter of its picks high-risk keeps three quarters of its score. Last, the QA check at the end of the video takes off whole points for each finding by how serious it is: 5 for a brace with nothing to anchor to or two panels in one place, down to 1 for embedded hardware that clashes.

Grades are on the curve of the final TIQ -- the field's average is a C, one standard deviation above a B, two an A, one below a D, two an F -- when the top is pulled away from the middle (the highest TIQ more than 25 above the median). When it is not, the standard scale grades instead: A from 90, B from 80, C from 70, D from 60, F below. A new project moves the curve. DNS means the project is published but has not been scored yet.
