Advance Lifestyles & Life Spoofing, How long is a day? How good is a mook? Options

[JoelHalpern]

So, Runner's Companion introduces the advanced lifestyles. Nicely decomposed, and quite useful.
There is a note that if you use this, then spoofing a life must be done component by componet.
The phrasing is a little odd, but it is not to hard to realize that you are supposed to use the level label for each component to decide the threshold for each spoof.
The text then says that the the interval is dramatically reduced for each such spoof.
It better be, since there are 5 different spoofs you have to do.

So, my first problem is that Unwired said the Interval was a day. The "much shorter" interval in RC is 6 hours. Huh? Yes, technically, 6 hours is 1/4 of a day (so we have a 25% increase in total time. I could live with that.) But people can not work that much of a day. I had assumed that any intervals that were given in days were 8-10 hour work days. How long is a day supposed to be?
The obvious conclusion is that the interval needs to be a lot shorter than 6 hours? (To get a 4:1 ratio with a 12 hour work day, you would need a 3 hour interval.)

So how long is a day supposed to be for things which are expressed that way?

One way out of this did occur to me. If you assume that the hacker is using a mook, then a day is indeed 24 hours. (Mooks clearly work around the clock.) Then 6 hours is indeed 1/4. But Unwired repeatedly indicates that Mooks are prone to making mistakes when doing non-routine tasks. It would seem that spoofing a lifestyle is non-routine.

Would most GMs allow an agent to use the rule of 4 for an agent? (Heck, would you allow the player to use the rule of 4?)
Would most GMs penalize an agent being used for spoofing a lifestyle? (Assuming a rating 6 comlink, using upgrading after play starts, and a 6 agent with rating 6 relevant software, probably pirated, the cahnge of a glitch on each test is 0.75%, or across 5 tests per month and many months, less than a glitch every 27 months.)
