Tip: The DR contribution of a single attack is
0.5^(x/n)
where
x = Number of hours since the attack happened
n = The attack's half life in hours = 8*oversend factor
The attack's base half life is 8 on Express. This is multiplied by the Oversend Factor, which is usually at least 1.1 for successful attacks, at most 1.0 for failed attacks. No matter what though, n cannot go lower than 6 or higher than 12 for Express. If you like Excel or something, you can do the clamping of n to between 6 and 12 with one of the following:
=MEDIAN(6, 12, 8*oversend factor)
=MIN(MAX(8*oversend factor, 6), 12)
Now all the above are in hours, you can use minutes if you wish. x and n divide by each other and whatever time unit you want to use cancels out anyway.
