Do you happen to have all the tapes and use a capture card?
I'm amazing you can tell which episodes and such all your
cels are from!

I have a TV cel of Misao and I have an idea where it's from
but I guess I don't really have the inclination to
watch through all the suspected episodes to find out.

Wow, you've got some really fantastic cels there!
Congrats on your collection ^_^
