You can easily throttle the waste on a merlin to increase recovery.  Just put a quarter turn valve on the outlet and set the ratio to what you want.

yes it can do but its the same as throttling the waste with a 4040.

obviously you wouldn't throttle it too much, certainly no more than 40% recovery.
