Very rarely is there any effort in India to collect statistics. We don't know how effective welfare programs were pre-Aadhaar and we won't know post-Aadhaar either. All we'll get from either side of the political divide is rhetoric.
Not disbelieving you, but would you have a citation documenting the progress ? Or were you making the point that if (hypothetically) it moved the needle from 95 to 99 that would be progress. Its not clear which one you meant.
I haven't seen any number that suggests so.
