An Audit (pronounced "od-dit") in real life is when a person looks at your bank accounts and makes sure you don't owe any money.
Only Cashbots use this move, most likely due to having to do with money.
This move looks exactly like Calculate and Tabulate, but the attack will have a sound.
Only Bean Counters and Number Crunchers use this attack, probably because an Audit is normally used by an accountant and both cogs have a meaning similar to an accountant.
