I've driven the supercharger highway coast to coast. Didn't read through all ten pages of this thread, but the answer, for me, is to divide distance by 50 miles ie over long distances, one averages about 50MPH when taking charging into account.
I've once done a spreadsheet, and the maximum speed you can average using the SuperCharger network on the West Coast (with the current spacing) is 59mph - by travelling on average at around 78mph, and targeting single digit stops (which is risky). Above this point you will lose more time to longer charging than the time gained with extra speed.
This is on a 85 with 19" tires. Other configurations will differ.
