I hate testing!

When I first started LF photography and wanted to learn the zone system, I went out and took god knows how many photos of the white house next door. I hated it. It made me not want to use a camera again.

I was hesitant about testing-as-I-go, thinking that I would make a bad exposure of the perfect scene, of screw up the development of the perfect exposure, etc. But so far, so good.

I have never even seen a densitometer, but I am interested in learning what the 1.- numbers mean when I read an article like the one Ed Buffaloe posted. Is there a source that explains the densitometer readings in a way that I could translate to zones or tones or something more practical for me?
