Work-search log: how detailed does it need to be?

I have been applying to about 8 jobs a week as a call-centre agent, but I am unsure what my state wants in the log. My state says to keep records for a year. Has anyone been audited?

Screenshots of the submitted application are handy backup when a posting disappears.

I record the date, the company, the job title, how I applied and any contact name. It takes a minute each and it covered me when I was asked for proof.
