Difference between two values in same column

Looking for a way in Power BI to calculate the difference between values in the same column. Need the day over day change to the remaining duration based on example data below.  Any help is greatly appreciated!

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

Would you happen to know how to modify this formula to exclude an increase in duration and only base the change off the original duration?
