Did not see your citation, whoops. Good to know Poi has been accurate so far. This makes it much simplier then. Just need to compare drop formations for different ships on the same page to see if anything's missing.

You're completely right. I forgot about Graf's restriction. Should have used Akizuki as my example then in retrospect. Still in this particular case and for this event, the underestimation is probably minimal (but who knows), since the admirals who got her would likely be clearing on a higher difficulty. It definitely skews the data for higher difficulties though. Thanks for point that out.
