Grey bars are non-letter outcomes — P/NP, S/U, incompletes. They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

| YIN, JUN | 3.34 | 3.35 | 36 | 1 | 56% |
| BAEUMLER, JOHANNES | 3.31 | 3.32 | 30 | 1 | 57% |

“Predicted” is shrunk toward the course average, which is itself shrunk toward the department — so an instructor with a handful of students sits near the course mean rather than topping the list.
