Understood, but does it matter that the timing of each injection
relative to the port open/close cycle changes when the injector is moved
from the block to over a foot away, & can it be adjusted like ignition
timing?

Good point, I missed the full implication of your original question.  No, the injection timing is not separately adjustable and I don't know if that would help in the case of large displacement from the port.  One important thing to note is that the air volume in the long runner can be larger than the intake charge at low throttle.  This makes it virtually impossible to properly time the injection pulse of a "long distance injector" without knowing the future, if you get my meaning.
