Work-search log: how detailed does it need to be? - 15 weeks in

I am keeping a spreadsheet of applications, but I worry it is not what the agency expects. I have read a lot of threads here and could not find my exact situation. Some days I only network by email or attend a job fair. Has anyone been audited?

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.

I was asked for my log once, after six months. Having it in a spreadsheet made it painless.
