----------------------------------------------------------
Our formula is:
t (in years) = ln(2^b/((k) ln(2^(1/1.5)))) / ln(2^(1/1.5))

where
k = Current Keys/s * 60 * 60 * 24 * 365.25
b = RC5-? (currently 72)
----------------------------------------------------------

1/6/04: 139281216064 Keys/s
k = 4.395389094 * 10^18

t = ln(2^72/((4.395389094*10^18)ln(2^(1/1.5)))) / ln(2^(1/1.5))

t = 16.77455246 years (16 years, beginning of October of the following 
year - sorry, previous calculation should have said "beginning of July of 
the following year")

Still, that's 5 months from the October calculation.

Just curious, what was the holiday on 1/5?
