\frac{146097}{400} = 365.2425~\text{Days Per Year}
\frac{20871}{400} = 52.1775~\text{Weeks Per Year}
\frac{6957}{1600} = 4.348125~\text{Weeks Per Month}


\frac{365.2425~\text{Days Per Year}}{7~\text{Days Per Week}}

Suppose a true cost model, accounting for all relevant information available at time t.

C(t) returns a distribution whose scale decreases with t, and C(0) maps to a single value. t>0 is time until the final payment.

Figure: lognormal distributions with the same location varied by scale.
