Activity map updates vs. Smart Definitions - NIS 2011

I hope that the announcement above means also that we can start discussing NIS 2011. :smileyhappy:

This is an architectural question, to head off potential questions in the future.

 

I noticed during the beta that the Activity Map was not updated for at least 4-5 days, while Smart definitions are ON (but possibly never, because I turned them off after such an interval).

 

My question is: when Smart Definitions are set to ON, the activity map data updates

a) less frequently

b) never?
