The frequency of the main reminder (VA-HOMELESSNESS SCREENING) is set to 1
and more recent than any positive Health Factor finding. 
 
Finding #2 (Current Stable Housing) and Finding #4 (No concerns about
housing in the near future) are required for a NEGATIVE Screen, which 
resolves for 1 year. If three consecutive screens are negative, the 
reminder will be resolved for 2 years - using the complex number of 
Function Findings - the sole reason for this Reminder Definition.
 
Function Finding 1 looks for 3 negative screens.

Function Findings #2 - #6 ensure that the NEGATIVE Screens are both 
consecutive and more recent than any negative screen.

With no resolution logic set on this Reminder Definition, it serves as a
means for resolving the main reminder (VA-HOMELESSNESS SCREENING) for 2
years . If this reminder evaluates as TRUE, then the main reminder is
resolved for 2 years, because the CF has a Match Frequency/Age of 2 years.
