Het lijkt mij juist dat er geen seizoensgebondenheid is. Er is geen duidelijk terugkerend patroon. Als je gaat kijken naar seizoensgebondenheid van tijdszones van meerdere jaren dan moet je over veel meer gegevens beschikken dan nu. Er zijn slechts 2 dieptepunten (extreme waarden) waar te nemen, met daartussen een tijdspanne van 40 maanden. Deze maken niet dat je kunt spreken van een terugkerend patroon.
