I don't know what this "man throwing a discus" is. I'm a noob i know I start a new game:
If it is ordered by function i know it produces units and in is enabled on phase 2 or 3 (since it is disabled on phase 1)
If it is ordered by phase i know only that it is enabled on phase 2 or 3 (since it is between a building of phase 2 and one of phase 3)
