I have no idea what PDSI is, i can only assume is some sort of ASI...like you said, it take a lot of time and training to learn the entire system, so it should have an ASI. I worked with the system for a year on a daily basis since i was 92A working in the SSA, and i don't think i learn not even a quarter of the system.
