My findings:
Jamaica, Macau, Mauritius, Mozambique, Senegal, and Seychelles all have had 1 leg and 1 NEL, the only countries to have a 100% NEL rate. Hong Kong is second with 3 visits and 2 NELs.
Argentina is the most-visited country not to have a NEL.
India, with 5, has had the most NELs. The USA, Russia, and Thailand all have had 4. The USA's 4 came from Leg 12s on seasons 1 and 2, and then 2 in the Family Edition. Finish lines are not included in the USA count.
Africa has the highest percentage of NELs. 32.26% of all African legs are non-elimination, followed by Asia with 31.82%.
*0* out of the 26 South America legs were non-elimination.
