Thanks, Rachel.
This ...
"Another thing that seems to come up is that during a quiz or exam inside scorm content, data isn't posted between questions but is submitted in bulk once the quiz is finished. So if you have content with a large number of activities, knowledge checks, or quizzes, this can be troublesome."
nailed it!
And, have suggested to course creators on the troubled system exactly what you have suggested.
And agree ... it is a 'push'. :|
Guess, they will have to make up their minds ... SCORM (which really does enhance the experience), but putzzes frequently (adds to support issues) ... or 'functional' ... known to work ... the Quiz in Moodle.
