Process accounting - did anyone ever use it?

When I worked at Refuge Assurance in Manchester, England we used process accounting on our Honeywell L66 under GCOS 3. I don't think we really did detailed charging, but we used the accounting records to divide up the cost of running the machine among the departments. I wrote the accounting routing .MBORT7 I think which was a small assembler routine that ran at the end of every job. It printed out the charges for store , disk and CPU and wrote to a journal.... I remember years after I left my wife, who worked in the company secretarial department, which is generally called governance these days, brought a print[out home detailing some shareholdings. After she had complained how useless the figures were, she then asked what the extra figures were on the bottom of the page. I explained it was a bit of code I wrote, that worked out the cost of the job!. She said as it was useless she was going to ask for a credit... ... I don't remember if she got one.... Dave G4UGM
