There are usually 5 to 12 people directly involved in this since more means you lengthen your chains of communication making the job longer!
In the good old days we didn't have electronic memory available to help us ~ now they have plenty of it to get in the way!
Then you stay awake most of the 10 days ~ and you get the revised rules published in the Federal Register (which is a separate task and that starts about 4 days from the end of the 10 day period of performance).
Looking at this they've gone into the on-line version of the rules and cranked in the rates under the EXISTING structure. That will change in a week or so after a totally new website is rebuilt ~ with a vast amount of proofreading by the world's foremost experts in postal rules.
So, thank goodness I am retired now ~ I think I went through this nearly a dozen times over the years ~ and once it's done you have piddling little edit corrections over the next 6 months ~ as people read your stuff and figure out everything wrong you did.
Top level Postal management thinks this is far simpler than it is and give no extra credit for it ~ which is why they usually burn out a rule writer in less than 5 years.
This is why I know what happened to Tony Weiner ~ he burned out then flipped out and then started sending e-mails of his packages!
It can happen.
Your last sentence=VERY FUNNY! LOL
