SCORM 1.2 Suspend Data--Seems Wonky to My Pea Brain

I have recently experienced the same problem with exceeding the suspend data limit. Using the (very helpful)  information in this discussion I switched on debug and did some tests.

The only way I found to reduce the data significantly was to set ALL slides to "Reset to initial state". For instance, a simple multi-choice question was sending 110 chrs back when the re-visit was set to "Automatically Decide". Changing it to "Reset to initial state" reduced the data to 9 chrs. My entire course went from over 10,000 chrs to around 1200 chrs. The course contains 147 slides including 9 sub-assessments, 10 result slides, 57 questions spread across 33 question banks. Passing the nine sub-assessments achieves a course pass via a final result slide.

Unfortunately the ability to review answers is lost when the slides are set to "Reset to initial state". So, I used a custom variable for each of the nine sub-assessments to hold a copy of the scorepercent variable for each. These were used with sliders to show how the student performed in each. If the student stops and starts the course these custom variables (and the slider positions) are maintained and they can pick up where they left off. Although they can't review their answers they can see which of the assessment topics they need to re-visit before attempting it again.
