How long until the Ex Inanis synergies change?

Can we get a rough estimate as to how long these 3 syns will be the current Ex Inanis synergies? I would like to know roughly how long we have to get our unicorns. At my current rate, I'm thinking a year? Obviously I do not expect them to stay for a year, just seems to be tough if you are focused on a certain gun type/syn/nano

I didn't find the right solution from the Internet.
