As with anything electronic, grounding plays a vital role. Just because it appears to be working properly that does not mean that it is actually working ideally. There could be a ton of errors within the digital signal (very easily caused by a poor ground and fluctuating dc voltage) causing a less than ideal digital signal. Digital signals provide a faster more precise signal, but are not as resilient as an analog signal so they are more prone to degradation.

I'm not here trying to sell grounding kits to anyone, but I do stand behind my belief that it has improved shifting from what I knew prior to installing additional ground wires. I bought the car used so for all I know the shifting response (my baseline in which to compare changes to) may have been degraded. I do not discount the fact that I may have had a poor/corroded ground before, and fixed that inadvertently by installing additional grounds which brought the shifting response back to the way it should have been from the factory.
