Hi! The reason Equatorial Guinea isn't included is that it has a island portion, as you know. I went through a dilemma and decided not to include it so that fellow JetPunkers wouldn't rage on my thinking I have insufficient knowledge. Also, the reason Gambia isn't included is that technically the pouring of the River Gambie into the ocean is wider and is technically considered part of the coastline. (I later noticed even Google Earth considers the wider parts as coastline)
