These are not the same as back in your day. These are daily charts showing projected volume for a particular route. Hard to memorize a new chart every day.
Preload manager says to go by the SPA label. No custom loading. Now who is showing a lack of common sense.
Both of these are basically the Mike and Ike of why preload is currently a disaster. Inconsistent labeling and the threat of management to follow these to a certain degree.
On a good day I will have the mental fortitude to read 1543, write 1543 and simultaneously check the address and make small adjustments based on my own route knowledge. When I lose sleep. It downgrades to the silly numbers. Managers will still harass you for not writing hins or moving stuff around too much. At the same time, the hins are actively detrimental in allowing oneself to focus in on the stops themselves.
The smart move for the company is to soft-abandon preload and try and get the new 22.4 drivers to load and deliver their own stuff. However this may not go well with local unions as they are not supposed to have their own bid routes in the language they were formed in.
For example, you could run an assignment consisting of 5 cars, 1 preloader, and 1-2 22.4 drivers (with one or both on a late-start).
(This is the opinion of somebody who is slated to drive this winter and has fully memorized a retiree's route as a year long pet project, I produce "good" loads but they are certainly not custom, immaculate, or done on-time lol)
