Requirements for going independent... (Score 1)

Some people have asked the inevitable 'HOW' question, as Matt doesn't really get into the specifics of making the leap in the video. Matt posted a follow-up on his blog (I'm his editor), which might be of use to this conversation as well: Four Requirements for Independence". He goes into the calculations needed for determining when and how to go independent (burn rate, replacement income, etc.). Curious to hear if the consultants here think it's enough to go on, or simplifies things too much.
