- The best way to report the anomalies is using the DRA format.
- To report asymmetrical periods in the PPAS, Bram Dorreman and I 
have used the following format :  give the total period in the usual 
colums of the PPAS line and explain the assymetrical period 
in the remarks :

For your observation :
- the 7 'odd' periods : (total 102.65) / 7 = 14.66 sec 
- the 7 'even' periods : (total 82.81) / 7 = 11.83 sec
=> Total period ( 7 odd + even periods : 102.65 + 82.81) / 7
   = 14.66 + 11.83 = 26.5 sec
