As a result of relatively (!) improved propagation south of the equator compared to the north and some other factors, including section choices made by some entrants, the latitude factor has reverted from an all-time high in 2018 to 1.68 for 2019. Prospective team captains and members should take note!

(I am attaching the spread-sheet used for this calculation, from which the movements since 2007 can be seen. you can request from me)
