Ubiquiti UCI pegged at 940 Mbps Down when paying for Gigabit 2x

Currently experiencing our Ubiquiti UCI pegging around 940 Mbps down after several restarts and attempts at different times of the day. We're currently paying for the Gigabit 2x and want to ensure speeds delivered to the modem are as expected. I know that the device is supported for Next Gen Speed Tier per the documentation listed here - Full List of Supported Devices.

Below (excuse the formatting nightmare) is the last speed test run against the cable modem from the Comcast.
