You know, maybe just changing one thing at time makes sense to him.
Changing the pump speed is a super simple change to achieve, then he can make a determination of the effect, and go from there.
Changing the gap on a mill is not that hard either, but it IS harder than adjusting a ball valve.
The OP has been given lots of options to help him out, it is up to him to choose where he thinks he will get the most bang for his buck, just because he is not re-setting his grain mill first does not mean that the idea does not have merit....unless of course, it has to be your way or the high way.......
