One thing you like to see is a progressive accuracy in manouvers
How can you assess "progressive accuracy" in an ILS when you are only given one attempt? Have you tried assessing progressive accuracy in a steep turn in the 737 sim? How about plus or minus 300 feet in the first half of the steep turn and plus or minus 100 feet in the second half with a total time for a 360 degree steep turn around 40 seconds. No way in all fairness to the student can a check pilot assess his "progressive accuracy" over 40 seconds.. Gut feeling perhaps and gut feeling has no place in an assessment.
"Progressive accuracy" as a assessment parameter is a myth and impossible to measure. Certainly not in a 40 minute test for a student who has never flown a jet simulator.
Occasionally one observes a student fly a credible 40 minute simulator assessment only to find a few weeks later when on a type rating course he/she fails to live up to expectations and has to be scrubbed. Simulator initial assessments are very much an imperfect art.
