Senpai ga Uzai Kouhai no Hanashi's chapter numbering on md doesn't match with the raws (bookwalker, Shonen Magazine Pocket)
Volume mapping:
<volume>:<chapter range>

1:1-20
2:21-40
3:41-57
4:58-77
5:78-99
6:100-121
7:122-140
8:141-159
9:160-178
10:179-195
11:196

this is as far as I could check (up to raw 193/md 196)
<md>,<raw>

65,64.5
66,65
... (+1)
78,77
79,77.5
80,78
... (+2)
--- v. 8
146.5,145
... (+1)
149.5,149
... (+0)
150.5,151
... (-1)
153.5,155
... (-2)
154.5,157

to resolve this:
if someone ever wants to translate the volume version, they should create a new title
