I wouldn't be surprised if that if that were the case. I did observe that it was getting shorter as the days passed.
well i found something out. When customers come in the door under there name is always 60 and then the time like 180s or 60s but on day 13 you can see a short time 0s so i think there is nothing made for the day 13 and other days after. might be missing some timers?
