That is not a very reliable way to show defence, it is used and killed all server unlike hammers that save for the end. All it matters in the end is the amount of def points you get.
This is from com1x3 in early 2021. My estimate is about 1.4 million crop defence trained for the server - phalanx + druids + heduans. I also had over 300k crop def left after server ended.
