I have noticed this in each version of the game I have played so far, and since it hasn't been fixed yet I figured I would report it in case it isn't a known bug.

When you have a ship with a destination, it will show how many turns it will take to get there.  Unfortunately the first turn (the green portion of the line, where it goes up to 1) is always two turns worth of moves instead of one.  This is true even in the Dev Streams, so I know it isn't just an issue with my game.  This is kind of a pain, because it looks like you can get someplace in one turn but often you cannot due to this bug.
