no misunderstanding on this end

Wanted to make sure you understand i was hoping for 63mph AVERAGE not the 75 mph AVERAGE you keep refering to in both posts.
We completely understand that you plan to have an average cruising speed of 75 mph, and you think that will allow you to have a total overall average of 63 mph.
We're simply telling you that based on millions of miles of experience, that's simply not likely. To have an average overall speed that high, you generally have to be cruising at closer to 85 mph, and have to be very dedicated to keeping your stops short.
We've explained a couple of times why your math is faulty, and you're basically making the same mistakes that a computer program uses. Specifically your calculations continue to assume you'll be able to travel at 75 mph for every minute you are on the highway, and going straight to zero for your stops. It ignores that there are many times where your actual travel speed will be lower, pushing your average down. For example, A 20 minute stop means at least 10 minutes where you'll be moving, but be doing significantly less than your cruising speed, as you prepare to exit, slow down for the off ramp, hit a traffic light or two, etc... (not to mention that a planned 20 minute stop is many times going to become 30 minutes when you've got a van full of people.) If things go exactly as you've planned, sure you might hit 63, but thing rarely go exactly as you plan.
In any case, your travel time will be what it will be. It looks like you're set with your plan, and we certainly wish you the best.
