I use 4 different tests after trying 16. I want the speed before it enters the router and when it is exiting. The big O has the exact result by 2mbs EVERY time. It doesnt work that way, speed changes in ms. Unless it is averaged over a wiiiide spectrum. It annoys me that they have so many using O, knowing that my speed is probably over 40gbs understated. It also shows stats almost the same with towers 1500 miles away, are we that dense.
