I really don't see any purpose in getting obsessive about turnaround time, on a turn by turn basis. The point is to avoid a chronic problem, not to make a big deal about individual turns.
A lot has to do with when the previous team's save is received. For example, a turnplayer might only have a 2 hour window per day when s/he can play. If the preceeding team delivers a turn right at the end of that 2 hour window, there is not much can be done but wait 22 hours till the beginning of the next window. If this happens every day then that team should be encouraged to have a backup turnplayer on a different schedule, but if it only happens once then why bother to make it an issue? All of us who have used computers more than a few years have had system problems now and then, again no point in making a big deal of it. I live in a place with seasonal thunderstorms and could lose power for several hours, that would also be something which should get respect from the other teams.
