sysback - estimate backup size only?

Is there a flag to send to sysback on the command line so it will return the estimated backup size and exit?
We're having issues with running to a second tape at a remote data center, and I want to alter the script to exit or add exclusions if the backup is over a certain size.

The other option is of course to kill the backup at a certain time, but I'd rather avoid that.

Oh, I tried mksbcd -e -E -T vg1 vg2 to estimate size, but it's inaccurate by an enormous degree.
