How to find Performance is at 85% of Target(which is 75%) for the last 3 out of 4 months DAX code

Hello All,

I am struggling to write a DAX code for my Measure called Rating 3 where it dynamically calculates whether Performance(SOL_KPI) is at 85% of Target(which is 75%) for the last 3 out of 4 months. 

My current Line & Clustered Column Chart looks like this:

As you can see, the SOL_KPI(Performance) is increasing towards Target for the last couple of months but significantly behind Target.

The DAX code should be written in such a way that as the data refreshes for the next couple of months like August, September, October, it should dynamically calculate Rating 3. 

The Dates Table is an artificial Calendar table I created using CalendarAuto function or I simply imported from the internal database which shows nothing but dates for this current year. 

Can you please suggest me any help here?
