Aggregate data based on condition to be computed on raw data

Hello all,

I am pretty new on Power BI and i am working on a report where i need to aggregate data based on some specific conditions:

Here is an example of what i am trying to achive:

Conditions are

Aggregate/group on continous data (based on timestamp) with 

Start > 90 to End < 20 (taking the lowest End value)

If there are increment ignore (as last case shown on image)

Hope that is clear enough.

I have tryied different approach with DAX expression, Visuals, M Query, with descrete results but not exactly what i am looking for. I have tried to find something similar on this Forum but unsuccessfully, i start to think that maybe is not feasable as i want, and i need to change approach.

Do you have suggestions? 

Thanks!
