Reservation - A Scientific Analysis

I am an Engineer. I believe that a scientific analysis is required to verify hypothesis before making grand political claims.
Consider the following analysis.

1. Collect data on a sample (not the entire population, but merely a sample) of people who have derived "considerable" benefit from reservation. Considerable benefit would include (but not limited to) entry into a premier institution and/or a job with annual income beyond a certain threshold
2. Divide this set into two: (a) Those who were NOT "first generation" beneficiaries - in other words those whose parents DID receive such benefits (b) Those who were at a financially stable position BEFORE receiving the benefits (which may be defined as those whose parents had a cumulative annual income beyond a certain threshold) and (c) Those who do NOT belong to categories (a) OR (b)
3. Find the ratio of (a) + (b) : (c). If this ratio is large (which I strongly suspect will), then reservation benefits those who were already "benefited" or in other words does not serve this purpose.

Of course, above analysis is actually easy to perform. But the harder part would be to find a leader who has the nerve to do it.

ps: Statisticians could help me in making this experiment "better". And such stuff has already been done, please let me know about the same.
