There are several different storylines that would be inconsistent/confusing when merged.
Having to add posts somewhere to the middle of a pool is also a pain when updating.
I think it's something like this?
Main1 - Kouji Manga - pool #8575; loose continuity
mini sidestory - goya - pool #9195
long sidestory - goya - pool #9885 - 30page long book
mini sidestory - akatsuki - pool #9196
mini sidestory - akatsuki - pool #9135
mini sidestory - haruna - pool #8743 - may be unrelated to the main storyline
mini sidestory - haruna - pool #8774 - sample, probably best to leave it in it's own pool until finished. may be unrelated to the main storyline.
Main2 - 2koma - pool #8747
long sidestory - tiny mutsu - pool #10036
Main3 - Today's Naval Base - pool #10101; doesn't seem to be quite the same admiral as Main1/2 (alternate universe with ooi as main char?)
prequel - pool #10181
long sidestory - pool #10684
mini sidestory - pool #9631
Main4 - Shipgirls' Daily Life - pool #9611
Unrelated sidestory1 - pool #9197 - Understand-a-shipgirl's-feelings unit
Unrelated sidestory2 - pool #10002 - Sketchy Kan-Colle 4-Panel Strip Manga
Unrelated sidestory3 - pool #10141 - Little Seven
The mini sidestories are kinda like extra chapters, and probably could be merged. The long storylines of 20+ pages could deserver their own pool, especially if it's an open ending and could be updated later.
Can be deleted?
pool #9746 - only 3 posts
pool #9579 - all posts already are inside a main storyline pool
