Equatorial countries have a maximum summer temp of maybe 32c and minimum winter temp of maybe 26c two seasons, a bit hot and a bit chilly. Which zone do these countries get placed. Example Sri Lanka aka Ceylon but Southern part of Far East Asia can go there, maybe the Southern most part of South Asia, Equatorial Africa and Central America. All of them seem to be placing themselves in zone11. Gives a false image.
