Hi John,
The two tech docs I mentioned in my earlier update, pretty much explains how the 'Use Stricter Rules' work. This is configured directly on the survey. See the link below with steps to create a surveys and how to link the survey to an Activity Notification:
How to Configure Surveys - CA Service Management - 14.1 - CA Technologies Documentation
I also think what you are really after is the 'Submit Cycle (Indicates to send the survey every 'nth' time.)' which is also a property of the survey template.
Hope this helps?
P.S. May I request that we stick to English as a medium of instruction for my benefit and many other Community Members. Otherwise I have to use Google Translate all the time to understand your updates ;-)
Kind Regards,
Brian
