Numbers might not make sense maybe, but bear with me.
The standing pipe tap at 50%, and the trigger at 50% gives x litres/min
With the standing pipe at 70% and the trigger at 30%, that would give the same litres/min
The only benefit comes in when the throttle (trigger) is at 100%, that would get more output with the max fuel screw (standing pipe tap) at 70% than 50%
Would that be right?

The factory setting not only needs to take power into account but engine longevity, emissions, passenger comfort and noise outputs too. changing one compromises others, as already advised by other posters.
Good points. Factory settings are a bit irrelevant in my case because my pump is from a 306 XUD9, and is now on a Dispatch DW8. The garage have done whatever tunings they've done, but I don't know it's optimal.
