Here is a link to a statement by Jim McFarland, who knows as much about mixture quality as any living human:

Port injection runs at 50-60psi fuel rail pressure, while TBI runs at 12-15psi. Plus with the injector next to and pointed directly at the intake valve, port injection does not give the fuel the opportunity to drop out of suspension while moving through the manifold. So with port injection you can set things up so the fuel evaporates at just the right time. |
That makes sense. Thank you for the clarification and the reading material
