Infra jumps are those times that a nation breaks an infrastructure upkeep cost barrier;
the most important ones are the 1000, 2000, 3000, 4000 and 5000 infra marks.
This tool will calculate what level your next jump will be; and how much you will have to save to make the jump,
without losing money due to the increased infra upkeep costs. DISCLAIMER. NO IT WILL NOT. MUAHAHAHA. I MEAN... SORRY.
