I would also venture that Victory's stats and deck differ a little from the other First Rates in light of her unique* design--other First Rates were built along preexisting design principles as floating fortresses, while Victory was basically an Invincible-family 74 (see almost all Slade 74s) pumped up on anabolic steroids, and Invincible and her Royal Navy progeny were if memory serves above-average performers for their time and size.
*Well, until copied for 1810 Boyne and 1811 Union--both of which I would say should use the same deck and stats, just maybe a slight Gunnery downgrade and some crew reduction in keeping with their lower rating as Second Rate 98's.
