Follow-Up on Rating System

One of the reports that I am running that seems to be fairly accurate (based on all of the August info) is RSRQ <= -20 AND RSRP <= 122 AND RSRP >= -140. The reason for using the -140 was due to some odd RSRP measurements (-200, -251) I was getting that appeared to be based on some condition that I can't explain. The -200 value and even the -251 didn't appear to be due to a bad signal, because I was still able to get normal download speeds/ping times when these conditions occurred. Since I do not know what they mean, I am going to exclude those results for now until I can find more information.

Some other reports that I am going to use for the rating system are as follows:

Slow Download Speeds (less than 1Mbps)
Any packet loss
Number of Times Carrier went to a non 4g/5g state (IE: 2G or 3G)
Thinking of some Others

Based on the preliminary data with these reports, I am sticking by some of the feelings I had previously but will post more details (including maps/reports) within the next day or so. The points I'm making below are not in a particular order (best versus worst).

When Verizon has a good signal, they can't be beat in regards to data (ping/downloads).
AT&T seems to be in the middle in regards to signal strength/quality and data performance but I have to say that Verizon seems to be catching up in this regard.
T-Mobile has the best RF/band performance with less dead-spots from what I can see but looking at average download speeds and ping, they are not the blazing fast speeds that tend to think. I admit that it is exciting to see 400Mbps and up download speeds (in the right areas with little congestion) but the average is no where near that. It is actually lower than Verizon and AT&T based on the tests I've done at this point. Whether this is due to backhaul or core issues, I don't know. My tests are limited to the areas I go to and live in (Maryland, Delaware, New Jersey, and PA right now) so other parts of the country will be different.
