Fine advice if you're at your career destination, or you've already got thousands of hours and either can't import yourself or won't pay someone to do it, but for anyone just starting off in their career, this is really bad advice.

Why?

Simple.

Job applications.

Eventually you'll be filling out many many apps, and no two apps are alike. Every company has their own way of torturing potential applicants when it comes down to breakdown of times; how much time do you have as SIC on Tuesday Nights while flying eastbound on aircraft weighing more than 41,000 but less than 65,000? How much PIC time do you have NOT acting as an Instructor? Etc etc.

Also, I don't know if certain companies still take this approach, but there are plenty of horror stories of otherwise successful candidates getting rejected because the math on the bottom line didn't add up. Sometimes by only a few hours.

In this day and age of smartphone app logbooks, why anyone just starting out wouldn't be using one is beyond me.
