What I did is just looked at already existing code that uses the fancyLogAdmin (almost all commands do) and used that to sort of figure out what things mean. I believe #s references a table, and like you said before, #A = calling_ply (usually an Admin) and #T = target_ply.
Honestly though, those are really the only ones you'll need I think. Unless you're trying to go for a specific thing.
