KC3 does have the values for Cn3 and Cn4, just hover your mouse over the LOS icon and it'll show the values, as well as the relevant maps that use them. Incidentally, that's where I got the value I wrote above (did you really think I'd calculate that manually?).

Also, the point of placing Jintsuu as FS isn't her yasen, it's her day battle potential - she's the only ship in the fleet capable of double attacks in day battle, and FS gain ~15% extra chance to trigger it. Not only that, she's well capable of sinking even the Ta-class should she aim at her with a double tap. Wasting that potential for the crappy boni a searchlight provides in this map isn't a good idea.
