Purely as a thought experiment, I've been playing around with a formula for calculating the redundancy score, and the following has been showing some promise:
where Hits is multiplied by 2 for ships with AA. The "30" is just a figure I've given as the average number of hits for a Raid level ship but it was a finger in the air estimate rather than a true average.
The resulting figure was then rounded up, unless the ship has better than Stealth 3+ or Dodge 5+, in which case it was rounded down.
I calculated the results for most of the Raid, Battle, War, and Armageddon level ships for EA, ISA, Narn, Centauri, and Minbari and the results were quite interesting and can be found at the link below:

For the most part, the ships came back with redundancy scores of:
1 at Raid
2 at Battle
3 at War
Where redundancy was lower than the PL average, it was almost always those ships with decent Stealth or Dodge scores (e.g. White Stars, Liati, most Minbari. In particular, the Delphi, WS, Liati, Leshath, Tigara all came back with 0 redundancy.
There were a few oddities however:
Command Omega - redundancy 2 (too low)
Explorer - redundancy 4 (probably ok though)
T'Loth - redundancy 3 (probably ok though)
G'Quan - redundancy 3 (assuming hits 65, otherwise redundancy 2)
Victory - redundancy 7 (too high?)
Ka'Bin"Tak - redundancy 6 (probably ok)
Adira - redundancy 5 (probably ok)
If I get a chance today, I'll add a some more fleets onto the spreadsheet to see what comes out.
