You can reset the cumulative consumption field in the q logvol f=d display.
Then run your server normally for 24 hours and check the consumption.  This
will give you a good idea how much recover log you might use in a 24 hour
period (the period between scheduled db backups).

The command to reset is

reset logconsumption
