Score calculation:
For each grid outside home grid :
each grid score = 1 + (qso distance in km average/20 000) + (grid distance in km from home grid/40 000) + (qsos number/200) * 1.25 if outside home dxcc * 1.25 OR * 1.1 if outside home State (US/Canada)
Example:I roving to help some good friends on FM. 5 qsos same DXCC, same States, grid nearby my home grid with a 2000km average distance:
(1+(2000÷20000)+(111÷40000)+(5÷200)) = 1.13 points
I taking plane for a foreign DXCC at 5000km distance to help as much possible stations to get the grid and DXCC. 40 qsos from differents linears with a 4000km average distance:
(1+(4000÷20000)+(5000÷40000)+(40÷200))×1.25 = 1.91 points
