This page studies the trigger rates & effectiveness of Artillery Spotting, based on credible in-game testing. An optimal use of Artillery Spotting could considerably improve your fleet's daytime combat performances.
This page studies the trigger rates & effectiveness of Artillery Spotting (弾着観測射撃), based on preliminary in-game testing. An optimal use of Artillery Spotting could considerably improve your fleet's daytime combat performances.
In brief, Artillery Spotting consists of two types of attack: Cut-In '''[CI] '''& Double Attack '''[DA]'''. When activated, the attacking ship receives a damage output (post-cap) & accuracy bonus. More detailed explanations could be found on the page [http://kancolle.wikia.com/wiki/Combat Game Mechanics -> Artillery Spotting] .

6. For standard BB(V)s, aka non-Yamato class BBs, radars could be replaced by '''AP Shells''' for a cut-in setup (Main / Secondary / AP / seaplane), which gives a 20% trigger chance bonus on CI. However, you could also use AP shells (or Secondary)''' '''for a''' <u>hybrid set up</u>''' (2 Main / AP (or Secondary) / seaplane). In the standard situation, the combined Artillery Spotting chance is about '''70%'''.

- Since AP shells are not accessible to CA(V), their maximum CI damage is '''''120% post cap''''' with radar. However, if secondary-gun hybrid is used for CA, it could be 130%, but reliability has not been tested. ''(Lower shelling accuracy expected? Same trigger rate as BB(V)?).''

# '''Level up your ships & marry them.''' Ship levels affect their individual LoS stat, and a high FLoS would guarantee your ships to DA/CI frequently in battles. Also, if we assume a linear LoS growth, lv150 ships would have 50% more LoS than lv99 ships. It means if your central fleet is at lv99, they'd probably have FLoS ~400 (+10% DA/CI chance). When they're leveled up to lv150, you'll have FLoS ~600 (+30% DA/CI chance).

# Since fatigue doesn't seem to penalize the trigger rates while DA / CI boosts shelling accuracy, you could use it to counter fatigue. For example, '''leveling your ships at 3-2a with red faces.''' This method could drastically speed up your leveling, but less resource friendly (more buckets & repair cost).

# If ELoS (effective LoS) is prioritized, you wish to have more seaplane bombers, and/or you don't have good radars, '''''equip an extra seaplane on your 4th slot''''' is usually a good choice.

# '''For newer players, hybrid setup is recommended''' since your FLoS (fleet total LoS) is usually very low, which in turn will greatly penalize your ship's artillery spotting chances. Hybrid setup, however, has the highest base trigger chances while not so affected by FLoS. However, you should always get AS+（制空権確保） and maximize your ship's firepower through modernization. Please be aware that using 2 x Main + 1 x Sec would shift your DA into CI in night battles, which is very dependent on luck stat & placement (flagship)..
