"SOS" (System of Objective Self-evaluation) Software Product 
is a practical application of the theoretical development "Principal Human Memory Model". It consists of three interconnected windows (interfaces). They define in sequence "Three Steps" in researching individual abilities of the user as stated at the random chosen time period or instance.

 Destination:
"Step 1" serves to identify initial activity values of the user's 7 personal memory types
"Step 2" serves to identify current activity values of the user's 7 personal memory types
"Step 3" serves to identify  detalized activity values of each of the 7 personal memory types of the user

"Step 1" Possibilities:
1). Calculation of personal activeness percentage for  7 basic Rhythms and obtaining advice under input date of birth.
2). Calculation of personal activeness percentage for  7 basic Rhythms and obtaining advice under input time of birth..
3). Summarized calculation of maximum and minimum personal activeness percentage values and obtaining advice for corresponding date and time. Procedure sequence>>>

"Step 2" Possibility:
1). Calculation of personal activeness percentage for  7 basic Rhythms and obtaining advice for date chosen at random.
2). Calculation of personal activeness percentage for  7 basic Rhythms and obtaining advice for given time of day chosen at random
3). Summarized calculation of maximum and minimum personal activeness percentage values and obtaining advice for corresponding date and time.  
4). Identifying individual periods within the specific year matching the given activeness percentage value for 7 basic Rhythms and obtaining advice for that rating. 
5). Identifying individual periods within the specific day matching the given activeness percentage value for 7 basic Rhythms and obtaining advice for that rating. Procedure Sequence >>>

"Step 3" Possibilities:
1). Calculating individual activeness values for 6 sub-Rhythms of either of 7 basic Rhythms in percentage scale and obtaining advice for a specific date, as chosen.
2). Calculating individual activeness values for 6 sub-Rhythms of either of 7 basic Rhythms in percentage scale and obtaining advice for a specific time of day of the date  as chosen.
3). Summarized calculation of maximum and minimum personal activeness percentage values and obtaining advice for corresponding date and time.
4). Identifying individual periods within the specific year matching the given activeness percentage value for 6 sub-Rhythms of either of the 7 basic Rhythms and obtaining advice for that rating. 
5). Identifying individual periods within the specific year matching the given activeness percentage value for 6 sub-Rhythms of either of the 7 basic Rhythms and obtaining advice for that rating. Procedure Sequence >>>
