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.

By instructor

Instructor Predicted Raw n Terms A range
LIU, KEFENG 3.87 3.90 18 small sample 1 100%
XU, ZHOULI 3.90 3.96 17 small sample 1 100%
SARKAR, SUCHARIT 3.91 4.00 11 small sample 1 100%

“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.
