At present you can't control the submission time any further than this, I'm afraid. This behavior is detailed here: http://docs.telerik.com/platform/analytics/integration/data-lifecycle/introduction#when-is-data-saved-and-sent
As it is, calling ForceSync() no more often that every 10 minutes is the most control you'll have.
The reason for this controlled submission is to save bandwidth and processing power.
Could I ask what your reason is for wanting to submit data more often? It's mostly something developers wish to do and mostly when initially integrating with Analytics, because they (we, I should say as I'm a dev too) are excited about seeing data arriving and being displayed. But once data starts coming in from a large number of real users then it actually becomes less important to see and analyze every bit as soon as it arrives and you become more focused on the accumulated, big picture.
To verify that data is arriving at all if you're without Fiddler, you can also take a look at the Live report: http://docs.telerik.com/platform/analytics/client/reports/live
