As GW stated, your tests look normal. Your tests that show a slower speed are that way due to them being in a peak usage period, when there are a LOT of people on using the system. During off peak your speeds are good, some of them well over the plan speeds.

Yes your speeds are right in what you should expect. Some even more than what your plan is advertised at. However if there is something you need more help with, or that you would like me to clarify, please let me know.
