I believe I went Metal Casting before Education and Fertilizer before Plastics.
That is a interesting strategy and result. I was considering that with Freedom you get the bonus growth from specialists, so Fertilizer is not really something of a priority. Also with the freedom SV strategy I was trading posting some non-river grassland for late game TP bonus to get 2/3 gold and 1 science, so fertilizer is something that gives little impact, but on this map Fertilizer is actually pretty strong.
