3rd to 110th is a gap which is, of course, strictly IMHO.
Parameters, there is nothing mine, its open for all to see. If you want that be defined clearly, then you can take into account the statistics, no of creative attempts, variations, permutations & combinations, time taken to create/finish a work, complex and challenging situations, much more.
For a perfect logical comparison, we need to hade a Raja db, comprising of data items not limited to
List of songs in time chronology order
Raga & other ICM parameters in each song, each part of songs,
WCM Parameters(Counterpoint, Fugue etc)
Instruments used
Average time went to finishing the work
Music Appreciation skills applied
Much more
All the above done for BGMs too.
All data items need to be sortable, searchable and all other 'able'.
Similarly create a db for Kamal;s work, then it would be 'somewhat' easy to compare logically.
