Mark,

The residence time equation goes like this-

P(r)= function (N(t) - N(t+r))dt

Where function(x-y) takes the value of 1 when x=y(x not equal to 0 and y not 
equal to 0) ie the site occupied and when x not equal to y or both x and y =0. 
N(t) index of water molecule found in the hydration site at time t.

First, seek define what you mean to calculate. If you can't write an 
equation down for it, you can't calculate it.
