Interesting. Here's a quick history of the top 5000 list:
http://tech.groups.yahoo.com/group/p...m/message/8692

Code:
Digits 	Date 		Time to next 10,000
50000 	Jun 22, 2004	13.1 months
60000 	Jul 26, 2005	10.1 months
70000 	May 30, 2006	8.3 months
80000 	Feb 09, 2007	3.1 months
90000 	May 13, 2007	1.5 months
100000 	Jun 29, 2007	6.7 months (average)
150000 	Apr 18, 2010	2.4 months (average)
200000 	Apr 14, 2011	3.2 months (average)
250000 	Aug 09, 2012	2.4 months (average)
300000 	Aug 11, 2013	???

From 50K-100K digits, the average time to increase 10K digits was 7.2 months.
Here's a snapshot of each year:
Code:

1-1-2002	24738				5333
