tmyanus ..welcome to the forum...
The reason that the average for verizon keeps going up is simple.....nothing defines what package people have....only the ISP.
So in your case..you happen to have a slower package than what the FIOS users are on...thus it sort of makes you look bad. And the more FIOS users that test....the higher the average for verizon goes...hope this clears it up for you..
I should add....that testing while you are logged in as a user allows you to look at your personal test results and see what your average is......not just the verizon average.
