I don't think that's a statistically significant difference.

Once a job is fouled up, anything done to improve it makes it worse.

Yeah, well with
$ md5sum /lib/firmware/RTL8192SU/rtl8192sfw.bin
68533bf8078a9e00966a78c9f2da4b9b /lib/firmware/RTL8192SU/rtl8192sfw.bin
$ uname -a
Linux jidanni4 2.6.33-2-686 #1 SMP Wed May 5 18:59:51 UTC 2010 i686 GNU/Linux
Before long, syslog will fill with
May 16 06:05:43 jidanni4 kernel: [ 643.862002] rtl819xU:Error TX URB for zero byte -166, error -2
and under a big apt-get upgrade with many different files,
your connection will soon become worse and worse till the point you
need to reconnect.

Default Bug#581554: firmware-realtek: Incorrect firmware

Also in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=579694#67 we
note that realtek has just released a new version of the driver, whose
notes say the driver is now ready for post-2.6.31 kernels finally. So
it would be best to have this new driver packaged, and also its
corresponding firmware too...

Yeah... I think I have that problem too... At random time and
depending on the use of the connection it will have to be restarted...
