User blog:Faeriedust/On the importance of sparkling

So I have read http://kancolle.wikia.com/wiki/User_blog:Homuhomu123/Shelling_Accuracy_Test_Results_%28Source_to_be_cited%29 and it sounds like these could be the formulae? Accuracy Term = 1 + sqrt(( Attaker's Lv - 1) * 5) / 100 + Equipment_Bonus / 100 'Evasion Term = Evasion / 75                ... for Evasion <= 37.5' '= Evasion / (Evasion + 37.5) ... for Evasion >= 37.5' >> Shelling Accuracy = Accuracy Term - Evasion Term >> Dodge Rate = 100% - Shelling Accuracy
 * Special note : Health state had been proven as irrelevant to shelling accuracy. See their previous exp't
 * Additional Rules : (not from the charts, but written on the blog post, see " 補足ルール" )


 * When the defending ship is sparkled, it receives 1.8 times of evasion value
 * When the attaking ship is under severe fatigue, accuracy term is halved.
 * When the attaking fleet is using double line, defending fleet's evasion values are halved. "

Dunno if this is accurate, but assuming it is true:

A ship with 70 evasion will have 126 effective evasion when sparkled. So sparkling takes the evasion term from 65.11% to 77.06%.

A ship with 100 evasion will have 180 effective evasion when sparkled. So sparkling takes the evasion term from 74.07% to 82.76%.

Now that's about a 12% jump in the case of a 70 evasion ship and a 8% jump in the case of a 100% evasion ship..

This means that if a ship had a 25% chance to taiha your ship on an attack before (seems to me pretty damned accurate tbh), it will now have a 13% chance to wreck your run.. Which means you basically just doubled your chance to evade that attack... If sparkling doubles my chances to win a run and halves the number of buckets I need to spend on a run.. seems extremely worth it.

Also, if that same ship that had 25% chance to taiha your 70 evasion ship before attacks your 100 evasion ship, it would have 9% less chance to hit, so let's say.. 16% chance. If you then sparkle, you get an 8% chance to get hit.. Again you've doubled the chances to evade..

The boost is only more evident the lower the enemy accuracy is.. which is probably why I've noticed that I take significantly less scratch damage (from weaker, lower accuracy ships) when I sparkle vs not.

So this idea that additional evasion has "diminished returns" can be pretty subjective (why I hate stats..).

I could do more math on other scenarios to prove my point, but basically it depends on the enemy accuracy.. If it's extremely high (for instance Re-chans opening torps) or extremely low (1-1 DDs), then yes you won't see much boost, but if you have decent chance to clear a map (3-5 maybe?), then sparkling will improve your chances and reduce damage pretty dramatically.

This is all assuming that formula is correct.
