Am I stuck with a Low to Middle lifestyle? Options

How many runs can be done in a month?

Lifestyle and program degradation of cracked software in Unwired make time a larger enemy in Shadowrun. My character would prefer to do 4 in a month so program degradation on cracked software and lifestyle costs are charged less frequently. I've read mixed things on how its supposed to work. Most recently I have been told that the "week off" is required after each run limiting the number of runs to 2 per given month.

Lastly, I've looked at http://www.shadowrun4.com/missions/players.shtml as well as "Calendar.pdf" and been unable to find anything on how it works. The only reference is "Characters are allowed to make one 'run per week in game time" but doesn't say if the one week cooldown is optional or mandatory.
