One of the biggest issues right now with how planners are building walks that are too long is because the packets data they are using is already falling behind reality, people are using the internet shopping even more in these tight times to save a few pennies, so if your attendence packet counts on the old walks are months out of date it will create havok for managers and posties doing the job properly.
So if your are in the know, choose the one that gets less packets, extra delivery points only make the difference on high call rate days (and in urban areas we should all be capable of delivering letters to ~3 houses per minute, depending upon the terrain and the path lengths to the door)... And on heavy days choose if you want to complete with o/t if required, or let your managers scratch their heads trying to find cut-off kings post revision who will more than likely be too shattered from their own walk.
