I disagree. I think for a newcomer it is best to learn to print using your eyes. Take the basics from a good book, and then practice and work.

Actually I think that is the best way regardless of skill/experience level so I'm with Doremus 100%. No need for enlarging meters, special timers, weirdo timing and estimation gimicks (developed by people to sell books) and other gizmos. Be methodical with a logical progression from test strips through work prints to final prints. If it takes more paper, so be it. You'll learn more too.
