I find this post very intriguing. I dont know if its worth anything or related, but..
We've encountered non completions with SuccessFactors (SF) ever since launch a year ago. It seems SF times the user out if no data is passed back to it within a specific time frame. If the user/content doesnt pass anything to SF within 15 minutes, its starts a 15 minute count down to expiration. After expiration, you can still be completing the online and not realise you've been timed out. If you use the popup window to deliver your course, you wont see the message warning you of a countdown. Do you see a message such as this @Video Nexus?

We made some SF system changes - unwillingly, but had to.

• "contentStructurePageExpireDuration" – which we changed from 120 (2 mins) to 600 (10 minutes) to try keep the page duration longer.
• "contentStructurePageKeepAliveInterval" change from 120 (2 mins) to 30 (30 seconds). We wanted to try keep the connection more frequent.
• Even though we extended the user session in SF (to avoid timing out the user), it gets overwritten by the overarching system - which I dont understand.

So there seems to be three sets of running timeframes that can affect a user. I've tried numerous times to replicate an issue and its almost impossible.

• We therefore no longer use storyline files in large/substantial amounts. They are nested iframes within a nested iframe, so we think are 'black holes' to SF, and possibly therefore trigger the system to time out and produce non completions
• We no longer use videos that play longer than 5 minutes (usually max 2 minutes). Are a black hole too it seems.
• We publish all our onlines and quizzes now in Rise and get no issues from quizzes anymore.

Admittedly, we still use a basic SCORM 1.2, but that will change as we need more data.

So, I am very nervous about our pending upgrade too and hyper keen to see what others wins may be here. Sorry if I'm a little off track, but feel like my sanity is sometimes at risk with SF.
