The distance between Petroupoli and Chalandri is too short (1km) to have an accurate calculation (circumference=171km !!!!)
The measures of those 2 schools on april 27 (Petroupoli and Chalandri) are partnered with the measure in Maricá on april 18.
Even if those measures are separated by 9 days, the results are better.
This proves once again that both hemisphers, north and south needs each others
