This is a flexible calculation, used in
work environments, which can be applied to all manner of things which
will make ones day easier.
eg. How much time to take off
work for an hour'
s lunchtime meeting (in this case, 6 hours)
It can also be applied to how many fucks to give.
eg. This client bores me. I would normally try my best but, by careful application of the Bradfield Permutation, it turns out I give zero fucks.
