[RC5] time spent on RC5-72

[bert]

With the amount of time passed so far with RC5-72,we are almost at the 
mark when RC5-64 finished, at 1757 days(when the key was found) or 
technically 1800 days when it was stopped. At the current rate I doubt 
if we will ever see 1% before the 10th year anniversary of RC5-72 or go 
as far as RC5-64 did in anyone's lifetime lol.
