Like I mentioned in my post, I was getting over 10Mbps over USB from my DInc's WiFi. This is way more than VZW can provide via radio.
I've yet to get anywhere near 1Mbps with VZW, so count yourself among the lucky.
What phone were you using?
I tested PDANet and Easy Tether and found that PDANet was very slow compared to Easy Tether. With Easy Tether I am tripling download and upload speeds of PDANet.
