If the standard is so unintuitive that you have to memorize it or look it up in a chart, you need a new standard.
How is 63-ltg-whatever intuitive? How do i know what 63 is? We have an architect that has all numbered layers 20 series is ceilings 30 is power etc. Their layer names are short, but other than that they are not very good. I have to have a sheet that tells me what layer is for what.
E-PWR-TXT electrical power text
E-PWR-EQP electrical power equipment.
EX-PWR-EQP electrical existing power equipment
ED-PWR-EQP electrical demolish power equipment
All the E's are in order and all the existing and demo electrical are in order. No chart to look up, just look at the layer names and you know what it is. The layer names are not that long either
No need for a manual that explains the standard, the standard explains itself. Also, all of our routines put things in on the correct layers to begin with. And it would be twice as much work to draft without the routines, so everyone uses them.
