I don't know if that's necessarily true. For instance, the time allowance to stop car, unbuckle seat belt and open bulkhead door is 11 secs. To grab one package is an additional 7 secs, and each additional package on top of that is an additional 5 secs. Nothing seems impossible about those numbers, and while there will be instances where you might not beat the 11 seconds (seat belt or door doesn't open right away), more often than not you could probably beat that standard. Same thing with package selection. You'll have your 4 40lb boxes you aren't getting out of the car in 30 seconds, but then you'll have 3 QVC boxes that will be done in 15.
11 seconds to walk each 11ft section; if you happen to do a mini sort, 15 or 22 seconds (I forget which). Time allowances used to be based somewhat on reality.
Not sure what they are based on now. Some I do, like they supposedly decreased the time allowed to open the bulkhead door by 4 seconds because supposedly the push button door saves us that much time. Often however, the door will not open all the way, if it unlatches at all, and really no time is saved. Who knows what other little goodies are in there.
