If i've understood your call flow correctly the CDR's required are
1,2,6 and 4,5,6. The key point being that the first call made is up
until both call legs are hungup (which is 6) whereas the CDR is
reporting its duration as the time up until the blind transfer was
initiated (which is 3).

As far as using the CDRs to identify that a blind transfer has taken
place my opinion would be that that is a secondary concern compared to
getting the call records accurate. There seem to be a lot of cases
where people are experiencing pain because of the incorrect CDRs for
their billing but I'm yet to see a post where someone is kicking up a
fuss because they can't easily identify whether a particular CDR was
involved in a transfer. It's would be a nice to have whereas incorrect
durations on the CDRs cost money.

Do you mean compare the differences between the CRDfix4 branch and
1.2? At the moment the blind transfer CDRs are the same for 1.2, 1.4
and CDRfix4 with all being incorrect in the same spot which is the
duration on the first call leg.

In case it's of any help if you have a Windows box available I have a
tool that can initiate SIP calls and carry out blind and attended
transfers with Asterisk. It does make testing a lot easier, I got
tired of playing hopscoth on my phones as well, now I just click a
button.
