@Bang Jan: Not in Volumes 4 or 5, but very likely in Volumes 6 or 7 or 8, but... they will be included, that's for sure.
@BT: I'll try my best to keep slow-mo repeats whenever they're really needed.
As for the question... probably around 10-12 minutes, which is not too long, I guess (at least it's not 19 minutes).
Oh, by the way, the slow-mo repeats will be slightly faster (1/3 of the normal speed instead of 1/6).
