Composting -- Carbon to Nitrogen Ratio?

Someone else had posted a question regarding the C:N ratio for composting. The expert replied that "the ratio is something like 6-8 parts brown/carbon-rich material to every 1 part green/nitrogen-rich material.” But I've read on SEVERAL other websites that the correct ratio is 30(C):1(N)... That's quite a big difference...??? Which is correct??

The generally accepted range of browns to greens for quick composting is 20 or 30 to 1. However, compost will happen at a much broader (or narrower) range of C:N rations. The ideal range mostly prevents odors and speeds the process.
