Which doesn't mean you can't put them there:
http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#formats

e.g. a %{Range}i and %{If-Range}i in a CustomLog would yield the Range
headers in the logs sent with the non-redirected request.

Next one would need to examine the behaviour of popular download
accellerators and check for their pattern in these fields. Most
prominently whether the last HTTP request logged has them or not.

You wouldn't be able to recover past information, of course (although
one could extrapolate the percentage of download accelerators back in
time).
