Maybe it was an overcast day and the those taking the measurements didn't allow for overcast, humidity and the like? There are Australian Standards for Db measurement, which allow for proximity to solid objects (such as walls, trees etc), humidity, overcast, wind, daily checking/testing of the meter etc - most of which get ignored by those who take measurements at race tracks.
Might be your friend was hard done by.
