So if you cherry pick data then SSR and OKW are middle of the pack?
Assuming the best possible starting location from only SSR and OKW rooms seems a little dishonest. Add at least a few minutes to the average for the people having to use the internal bus loop and then run the data without Disney Springs as an option, which is obviously doing a lot of heavy lifting too as they are Disney Springs resorts, but most people only care about proximity to the parks. My head math says they are now bottom of the list for time to the parks or very close to it. Poly may still be the last though.
But the Poly Monorail time to Epcot seems a bit long. Personally I would rather walk to the TTC from anywhere at Poly than take the monorail the long way around. We did it from the Poly Tower last month and it was still great, and I think it was much less than 30 minutes. You could alternatively assume the best poly location for travel like you did with SSR/OKW and assume they are staying in the closest room to the TTC for the Epcot monorail times, and take the express monorail time only vs the resort monorail for MK.
Then you get into the argument about "feeling" the magic. It just seems so much nicer to be able to walk to, or ride a boat/monorail to a park. Even if the time isn't that much faster
