Based on Zeraphix's replays, we have the following: http://kc3kai.github.io/kancolle-replay/battleplayer.html?fromImg=http://i.imgur.com/gCL5W8W.png

In night battle: "api_damage":[-1,[0,5],[229,220],[65,29],[6,0],[1],[7],[4,-1,-1] "api_cl_list":[-1,[1,1],[1,1],[1,1],[1,1],[1],[1],[1,-1,-1]] "api_eParam":180,0,120,190],[100,0,85,100],[100,0,75,105],[100,0,65,110],[70,88,60,100],[55,0,40,65 firepower torp AA armor in that order so we're dealing with 100, 105, 110, 100 armor. these two hits were dealt on [8,8] second ship equip is [565,553,539,567,-1] [565,553,539,567,-1] = 5inch Coastal Gun 4inch Twin Dual Purpose Gun Mount + CIC 40mm Abyssal Twin Autocannon Mount Coastal Radar coastal gun has armor mod of 2 so 102 is your base armor rolls 72-132 armor. since standard ap bonuses don't apply in yasen and crit is out we only need multiply FP by da bonus Guns used were proto 35.6 and proto 41 no mod, with maxmod T91 AP shell 40 + 99 + 3 + 8 = 150 FP (229+71)/180 = 1.67 (220+132)/180 = 1.95 so 1.67 < AP shell modifier < 1.95 if multiplicative if it's additive, then we take 352-180 or 301-189 then it'll be an additive bonus of 112 < x < 172 or if said addition is before DA bonus then we'll have 93 < x < 143

Conclusion: The AP shell either adds damage by 67-95%, or base firepower by 93-143, or final damage by 112-172.
