 * Assuming that formation damage bonuses do not apply in night battle, twin WG42 has at least a 1.63 postcap modifier on Central Princess. (Twin Wurf+twin 5★ guns = (77 + 112 + 24) damage, which is 179 after accounting for 0.7 chuuha and 1.2 DA mod. Minimum armor roll on Central is 189. Damage dealt is 72, or 102 damage before 46/65 ammo mod. Minimum postcap bonus = (102 + 189) / 179 = 1.63.) Since the modifiers are 1.25 for single Wurf and 1.60-1.65 for twin Wurf on Supply Depot Princess, it is reasonable to assume Central Princess has the same WG42 postcap modifiers as Supply Depot Princess.

This analysis has several minor innacuracies, although the conclusion may not be wrong.

According to the extracted replay API calls "api_touch_plane":[102,-1] was invoked meaning the allied fleet had night scout contact (and enemy fleet had no night contact). In addition, we can learn from the API data the last attacker Tone did not true crit ("api_cl_list":[-1,[1,1],[1,1],[1,1],[1,1],[1,2],[2,1],[1,1]]).

77 base firepower + 110 WG firepower + 24 gun+upgrade firepower + 5 night scout firepower = 216 attack, premodifiers

216 attack * 1.2 DA mod * 0.7 chuuha mod = 181.44 attack postmodifiers, assuming no other pre-cap modifiers.

Possible armor range on 270 armor target is 2160.7*270=189 to 1.3*270-.6=350.4.

Ammo after 3 surface battles and 1 air node is 22/65 (expenditures from air nodes are rounded up), translating to around 67.7% damage.

Assuming post-cap WG modifier of 162%, attack becomes 293.9 post-modifiers. Damage range before ammo correction is scratch ~ 104. After ammo modifiers damage range becomes scratch ~ 71. The observed damage 72 falls very slightly outside this range.

Therefore, there are two possibilities:

1. There are some (possibly minor) innacuracies in the damage formulas I've employed.

2. There is multiplicative bonus of greater than 1.62 for WG against Central Princess (damaged). I'm unfamiliar with where the 1.62 number came from, so it's possible wikiwiki is incorrect on this point.

In any case it seems reasonable to assume there is a bonus at least of the same order as on Supply Depot Princess. It would be more informative if we looked at more data encompassing different WG counts to see what non-critical non-scratch damages are achievable in 1 WG and 2 WG cases, and whether that alligns with the known 1 WG and 2 WG bonuses on Supply Depot Princess.
