The unit of measurement is a set of episodes which appear in contiguous magazines. For example, Mercy Height is split up as follows:
Mercy Heights 15 episodes (Progs 1033 to 1047) 91 pages
Script: John Tomlinson, Artist: Various
Featuring: Tor Cyan
Art by Walker/Sullivan/Currie
Dead of Winter 1 episode (Prog 1124) 10 pages
Script: John Tomlinson, Artist: Googe, N
Featuring: Tor Cyan
Mercy Heights Book 2 Part 1 5 episodes (Progs 1133 to 1137) 30 pages
Script: John Tomlinson, Artist: Trevor Hairsine
Featuring: Tor Cyan
Mercy Heights Book 2 Part 2 10 episodes (Progs 1139 to 1148) 61 pages
Script: John Tomlinson, Artist: Various
Featuring: Tor Cyan
Art by Lee Sullivan (6-10)
Because it didn't appear in prog 1138, Book 2 has two entries in the database and therefore you can record 2 separate votes, whereas book 1 was printed in a single run and therefore can only be voted on once.
I did consider making a new entry every time one of the creators changed but that would have been a nightmare on those stories which have a different artist every week or two artists alternating.
I also considered not spliting stories at all, but then I would have had to code which progs each story skipped to avoid it showing up on the wrong prog profiles.
One day, when I have time, I'll deal with the 'various' entries in the credits in a similar way to the costars.
