The golden question now is: What to do now?
Haven't you noticed already?

argument/arg that it has given you and the way it corrects itself?
I'm seeing that you're quite versed on using commands so I'll just point you to btcrecover's help menu:
python btcrecover.py -h
That'll show you a list of available command line arguments and with explanation of each.
