Can someone indulge me and explain, from a mechanical standpoint, why this position must be so precise? I'm sorry but my type "C" personality prohibits me from simply accepting without understanding.

I can see that backing it out too far could possibly prevent the clutch from releasing when you pull the lever or screwing it in too far could make the clutch slip constantly and maybe cause a bind in the master cylinder when you actually pull the lever. Is there more to it than that? Is it a matter of tenths or a matter of thousandths?
It's actually a reverse situation.
The screw controls the return of the piston in the clutch master.
There is a hole in the assembly that allows the return of fluid to the master.
If you adjust the screw and prevent the return of fluid when the slave heats up due to engine heat there is no place for the expanded fluid to go. The clutch will then start to slip because the slave piston has to move to accommodate the larger volume of fluid.
You
can adjust it to a point.
It's just not that much.
The other downside to using that screw is you reduce the amount of fluid moved and can cause clutch drag making neutral difficult to find.
