Default Wi-Fi Link Speed 5GHz - anyone seen over 72Mbps?

When connecting to a 5GHz wireless network, has anyone ever gotten a Link Speed (tap the wireless network in Wi-Fi to see it) over 72Mbps?

I am sure I have set my router up right (40Mhz), but I still can't get the LG OG over 72Mbps. I think it should go to 150Mbps, unless there is a hardware limitation.
