Every international freedom/democracy/human-rights 'index' is reducing India's rank/score every year. They are using the formula:
-X = X0/Y
Where:
-X = Reduction in India's score this year
X0 = India's score last year
Y = Number of years they expect the Modi/BJP/NDA government to last
-X = Reduction in India's score this year
X0 = India's score last year
Y = Number of years they expect the Modi/BJP/NDA government to last
So India's score will go on decreasing every year and reach zero in the (estimated) last year of the Modi/BJP/NDA government.
Also we can use this formula to find out the value of Y for the authors/creators of each such 'index'.
