I also see that CA uses this same opcode. Quite right. One of the most important and fundamental measures was completely left out of the PGN standard. The symbol 'acd' is used by a large number of programs. Hiarcs uses 'dep' and since there is no standard for it, we can hardly say that is any better or worse. You surmised correctly that acd is the program's notion of analyzed depth in plies.
