Wat Q7 betreft kunnen we wel degelijk stellen dat je de 4 reeksen test op de constant + random component. Verder wordt hier geen enkele conclusie uitgetrokken.  
 
Wat Q10 betreft is de feedback zowat gelijkaardig. Je staaft de bevindingen enkel met de zaken die je waarneemt. Een andere grafiek en methode gebruiken had hierbij aangeraden geweest. Voorbeeld 'autocorrelation plot'.
