Fusion Upgrade, Los Angeles We converted over last week. At 10k feet (the last block before Verizon, alas), we went from 640/250kbps to 3.1/.8 Mbps.
Not fantastic, not as much as theoretically possible, but a phenomenal improvement over the status quo.

First, congratulations, and welcome to the club.
Now, I switched over from AT&T to Fusion a couple of years back. On a 9,156 foot loop, I had 3008/512 service from AT&T. Attenuation/SNR fell just short of qualifying for 6016/768 service. Fusion took us to 4.9 Mbps.
AFAIK, AT&T doesn't have a 640/250 plan. Their tiers are 768/384, 1536/384, 3008/512, and 6016/768. If you fall a little short, as we did, they put you on the next lower tier. I am guessing the best you could have got from AT&T was 1536/384. Your Fusion speed is consistent with being just a city lot too far for AT&T 3008/512 service; Fusion 3.1 Mbps is about double the AT&T max tier, as it was for our shorter loop.
I expect your SNR now is right around 6.0 dB, and your sync is right around 3600 kbps.
