Hi Winston.
I believe the default is for spoor to "Store question state" this adds a lot of data to the suspend data string as each question adds its identifier (about 20 chars) to the string e.g. "CIhOiBYQEEA4MfCgi",
I dont think theres a lot to be gained from compressing the string... its really a limitation of SCORM.
However it should still save progress to some degree - e.g. if the complete it should show as complete.
However some LMSs will close the course if there are any SCORM errors which would include trying to save too much suspend data.
Which LMS are you using?
