observation - class average (gradebook items) does an average of the total scores divided by the number of students. I noticed this in averages of 2 tests I did, where some people had not submitted tests yet, which gave 0s for their scores. this brought the class averages WAY down below what the average would have been had the total scores been divided by the number of submissions. oddly, there is also a log sheet on the gradebook items summary page for each of the tests, indicating a 0 score was recorded by me when I should have had nothing to do with the scoring. the scoring should have been done automatically in tests & quizzes.
the only commonality in these 3 students was they were added to the site after I had been playing around on it for some time, when I needed extra bodies to populate groups/sections.
Note: these grades are occurring from graded items outside of Gradebook, e.g., quizzes.

after creation, some items seem to take longer than I remember to show up on the site. for example, in creating graded and ungraded assignments, the graded ones showed up almost immediately in the assignments list. the ungraded one tool a long time...like perhaps more than 30 minutes. despite clearing the cache, reloading and login & out.
