If I'm setting up a best-effort connection, what should I use for the PCR?

I've been told that it should be set to the line rate, because otherwise the
switch can use GCRA to tag based on the provided rate, and any cell other than
the first in a burst will be tagged. (since it has no specified burst size)

On the other hand, UNI 3.1, 3.6.2.4 says that "the user need not conform to the
signalled PCR and the network may enforce a PCR other than the signalled PCR",
which tends to indicate that the PCR is more or less meaningless to the switch. 
However, a PCR set to a reasonable level (representative of how I intend to use
the connection) could be helpful to the destination for a number of reasons.
(To accept or reject connections, or allocate resources)

Is there an accepted way to deal with this value?  Any pointers to references
on the topic?

Thanks in advance.
