Practical speeds nowhere near "symmetric" nor consistently high for 1Gbps service
A few days ago, I engaged in a chat with ATT about my 1Gbps service. That day, speed tests indicated I was getting 58Mbps down and 150Mbps up +/- a few Mbps. I indicated I was used to practical service speeds of many hundreds Mbps up and down, and it was generally pretty symmetric. When I say many hundreds, I mean more than 700.
Today I perform another speed test and I get 448Mbps down and 849Mbps up. This is of course much better, but suggests some manipulation is being performed. My equipment, my connections, and my load on my network are a virtual constant.
Of course they had me log into my Router/Modem (Arris BGW210-700) and of course the modem's speed test is symmetric and close to 1Gbps.
And so, what is really going on here?
Thank you for your assistance.

Is your PC connected directly by ethernet cable to the Arris modem when you do these tests? Nothing else running on the PC? Tried all the ports on the modem? Curious issue, assuming your are connected straight to the modem by cable then it could be the AT&T modem is faulty, or their service is terrible, or they are using filters on your traffic (it's in their disclaimers).

Yes, I'm connected hardwire to the Arris.
I did another test. 515Mbps down / 795Mbps up.
The upload speed is what I was seeing when service was first established. But the download speed as you can see is inconsistent (no change in configuration or use of my local network). And it's still falling below the 600Mbps that ATT claims I should be receiving (I was receiving 700+ back when service was installed).
Even when I was using WiFi and using my LG V30 smartphone, I was getting 600+ Up/Down. I can only conclude there is bandwidth shaping of some sort occurring or hardware issues upstream of the connection to my home..
Insights welcome.

Today another test. Same loading (practically nothing) on my local network. 540Mbps up / 448Mbps down. Not really the Gigapower results I expect, when comparing my initial results upon installation with my service now. Initial results were in the ballpark of 750Mbps up/down.
My plan is effectively 1/2Gigapower. 😞
Someone in the know, please, just hop in and tell me what's happening so that expectations which were first set can be appropriately calibrated.
Edit 30min later... Another test: 529Mbps down, 899Mbps up. Yep. No change to my network. Amazing. A 100% increase in upload speed.
Of course, the speedtest results are going to be a function of the server to which the test connects to, hence, the difference in speedtests conducted within the modem/router itself, and via an application hitting a particular AT&T server in a nearby county. However, you expect that in general, for 1Gbps service, the speeds are going to be consistent and in keeping with the results one achieved when initially establishing service...
So now, the upload result meets my expectations, but the download speed?

Fiber installs are probably the same world over.
Watch this video for a little insight, even though it is UK based.

A line comes out from the ISP's central exchange into your neighborhood. From there everyone gets connected to a hub. I've seen it in front of my house (underground) as I am by the road and the neighborhood is still under construction. The hub can also be on poles in parts of the country. These local hubs might connect back to other hubs\switches before it gets back to the central exchange.
Basically, like coax, you are sharing bandwidth with your neighbors, and speeds are dependent on the hub(s) you are connected to and traffic at that time...
