Cirrus... is it time for certification review?

Doing a little math:

And in the past year, the numbers have gotten worse.
Accidents and incidents (from theFAA and NTSB databases)
1998 2000 2001 2002 2003 2004 2005 2006
SR20 1 0 2 3 0 1 2 7
SR22 - - 2 2 3 8 12 15
TOTAL 1 0 4 5 3 9 14 22
rate (%): 50 0 2 1 .3 .6 .7 1
fleet size: 2 7 206 514 902 1491 1949 2323
SR22 fleet 121 383 687 1180 1560 1848
SR20 fleet 2 7 85 131 215 311 389 475

So, each year a bit less than one percent of the fleet bites it. The
rate seems to be increasing slightly in the last few years, but the
sketchiness of this data precludes a conclusion based on that.

To compare with the Cessna fleet (bearing in mind the errors in the year
data due to registrations), I'll just add the last five years of fleet
size, getting something like 125,000. Five years of accidents at a 3/4%
rate (the last five years of the Cirrus rate, eyeballing it) would imply
something like a thousand C-172 crashes.

So, were there "something like a thousand" C-172 crashes in the last
five years?

summed for SR20 and SR22. I added the total fleet size (by
airworthiness date), figuring it was unlikely that the Cirrus fleet
would have accumulated many date errors yet due to sales.
